Ligand effects on the stereochemistry of Stille couplings, as manifested in reactions of Z-alkenyl halides

Unexpected losses in stereochemistry from Stille reactions involving Z-alkenyl halides have been shown to be ligand dependent. A new set of reaction conditions has been developed that, in most cases, leads to highly stereoselective cross-couplings under mild conditions, along with improved yields.

A Conformational Restriction Strategy for the Identification of a Highly Selective Pyrimido-pyrrolo-oxazine mTOR Inhibitor

The mechanistic target of rapamycin (mTOR) plays a pivotal role in growth and tumor progression and is an attractive target for cancer treatment. ATP-competitive mTOR kinase inhibitors (TORKi) have the potential to overcome limitations of rapamycin derivatives in a wide range of malignancies. Herein, we exploit a conformational restriction approach to explore a novel chemical space for the generation of TORKi. Structure-activity relationship (SAR) studies led to the identification of compound 12b with a ?450-fold selectivity for mTOR over class I PI3K isoforms. Pharmacokinetic studies in male Sprague Dawley rats highlighted a good exposure after oral dosing and a minimum brain penetration. CYP450 reactive phenotyping pointed out the high metabolic stability of 12b. These results identify the tricyclic pyrimido-pyrrolo-oxazine moiety as a novel scaffold for the development of highly selective mTOR inhibitors for cancer treatment.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 95464-05-4 is helpful to your research. Reference of 95464-05-4

Asymmetric crotylation reactions in synthesis of polypropionate-derived macrolides: Application to total synthesis of oleandolide

Complete details of a convergent asymmetric synthesis of oleandolide (1), the aglycon of the macrolide antibiotic oleandomycin, is described. The synthesis has been achieved through the assembly and coupling of the left- and right-hand subunits 12 and 38, respectively. These subunits were prepared from chiral silane-based asymmetric crotylation reactions to control the stereochemical relationships. The left- and right-hand subunits (C1-C7 and C8-C14) were brought together through a Pd(0)-catalyzed sp3-sp2 cross-coupling reaction between the zinc intermediate 40 and vinyl triflate 38 to give 27. This product was converted to seco acid 42a and cyclized to lactone 35 under Yamaguchi conditions. This material was then epoxidized with m-chloroperbenzoic acid (m-CPBA) to install the correct C8 epoxide as a single diastereomer, which after a short deprotection sequence completed the synthesis of oleandolide.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex, you can also check out more blogs about95464-05-4

Palladium-Catalyzed Intramolecular Self-Alkylation of Polyfluoroarene via Heck and Decarboxylation Process

An efficient palladium-catalyzed cyclization and polyfluorophenylation of gamma,delta-unsaturated polyfluorobenzoyl oxime ester via iminopalladation/polyfluorobenzoyloxy decarboxylation cascade reaction is developed. The protocol provides a practical and atom-economical access to a broad scope of various polyfluorophenylated dihydropyrrole derivatives. The reaction effectively utilizes the polyfluorobenzoyloxy leaving group as polyfluorophenylated source for the first time, precluding the need of additional polyfluoroarene. This is the first example of the introduction of electron-deficient arenes in the further transformation of Narasaka-Heck-type reaction. Additionally, the reaction is conducted in a short time.

Cleavage of homometallic and formation of heterometallic M-M bonds. Serendipitous syntheses of bimetallic MnPd(mu-PPh2)- (CO)4(eta2-P-P) (P-P = dppm, dppe, dppf) and polymetallic Mn2Pd2Ag(mu-Cl)(mu-PPh2)2(mu-d ppm)(CO)8

Condensation of [Mn2(CO)8(mu-PPh2)]- with Pd(II) assisted by Ag(I) leads to cluster disproportionation, viz. Mn2Pd2Ag(mu-Cl)(mu-PPh2)2(mu-d ppm)(CO)8 and MnPd(mu-PPh2)(CO)4(eta2-P-P) (P-P = dppm, dppe, dppf). The former shows a distorted bow-tie structure with two heterometallic triangles {AgPdMn} sharing an Ag center. The unexpected phosphide migration across different metals holds the key to the cleavage and formation of metal-metal bonds. The bimetallic complexes are stabilized by all common diphosphines whereas the polymetallic structure is isolated only when supported by dppm. The latter shows three different types of heterometal-metal bonds Ag-Mn (2.6938(4) A), Ag-Pd (2.7637(1) A) and Mn-Pd (2.8183(9) A) (average values).

Localised to intraligand charge-transfer states in cyclometalated platinum complexes: An experimental and theoretical study into the influence of electron-rich pendants and modulation of excited states by ion binding

The neopentyl ester of 1,3-di(2-pyridyl)benzene-5-boronic acid (dpy-B) is a useful intermediate in the divergent synthesis of N^C^N-coordinating, 1,3-di(2-pyridyl)benzene ligands, HLn, that carry aryl substituents at the 5-position of the central ring. The platinum(ii) complexes, PtL nCl, of several such ligands have been prepared, incorporating pendant anisoles, arylamines, an oxacrown, and an azacrown, all of which are strongly luminescent in solution at 298 K. The emission of the complexes is partially quenched by oxygen, and all of the compounds are very efficient sensitisers of singlet oxygen. The quantum yields of 1O2 formation have been measured on the basis of the intensity of the O 21Deltag emission at 1270 nm, and are in the range 0.25-0.65. Density functional theory (DFT) calculations have been carried out that include the effect of the solvent, on the unsubstituted complex PtL1Cl and on the derivatives incorporating p-dimethylaminophenyl and phenyl-15-mono-N-azacrown-5 pendants (PtL9Cl and PtL12Cl respectively). Absorption spectra have been simulated on the basis of the calculated singlet excitations: they closely resemble the experimental spectra. In particular, the DFT successfully accounts for the appearance of low-energy absorption bands that accompany the introduction of the aryl pendants, indicating the participation of the aryl group in the HOMO but not significantly in the LUMO. The calculated lowest energy triplet excitation of PtL 1Cl is close to the observed 0-0 emission maximum of this complex in solution. Taking together data for this series of complexes and related compounds previously studied, the energies of the lowest-energy spin-allowed absorption bands are shown to correlate approximately linearly with the oxidation peak potential. The emission energies show a similar correlation in toluene, but in CH2Cl2 the value for PtL9Cl is anomalously low. The differing emission properties of this complex in the two solvents suggest a switch to a TICT-like state in CH2Cl2 (TICT = twisted intramolecular charge transfer), stabilised in the more polar environment. Transient DC photoconductivity measurements confirm that the dipole moment of the triplet excited state is larger in CH2Cl2 than in toluene. The azacrown PtL12Cl displays similar behaviour. Binding of metal ions such as Ca2+ to the azacrown unit of this complex leads to a pronounced blue shift in the emission, which can be readily understood in terms of the large increase in the TICT energy that will accompany the binding of the metal ion to the lone pair of the azacrown nitrogen atom.

Kumada – Corriu coupling of Grignard reagents, probed with a chiral Grignard reagent

The Grignard reagent 2, in which the magnesium-bearing carbon atom is the sole stereogenic centre has been coupled with vinyl bromide under Pd(0) or Ni(0)-catalysis to give compound 3 with full retention of configuration. Coupling using Fe(acac)3 or Co(acac)2 as catalyst was accompanied by considerable racemisation. These findings are discussed with respect to a dichotomy between concerted polar and stepwise SET transmetallation pathways.

Hit Optimization of 5-Substituted-N-(piperidin-4-ylmethyl)-1H-indazole-3-carboxamides: Potent Glycogen Synthase Kinase-3 (GSK-3) Inhibitors with in Vivo Activity in Model of Mood Disorders

Novel treatments for bipolar disorder with improved efficacy and broader spectrum of activity are urgently needed. Glycogen synthase kinase 3beta (GSK-3beta) has been suggested to be a key player in the pathophysiology of bipolar disorder. A series of novel GSK-3beta inhibitors having the common N-[(1-alkylpiperidin-4-yl)methyl]-1H-indazole-3-carboxamide scaffold were prepared taking advantage of an X-ray cocrystal structure of compound 5 with GSK-3beta. We probed different substitutions at the indazole 5-position and at the piperidine-nitrogen to obtain potent ATP-competitive GSK-3beta inhibitors with good cell activity. Among the compounds assessed in the in vivo PK experiments, 14i showed, after i.p. dosing, encouraging plasma PK profile and brain exposure, as well as efficacy in a mouse model of mania. Compound 14i was selected for further in vitro/in vivo pharmacological evaluation, in order to elucidate the use of ATP-competitive GSK-3beta inhibitors as new tools in the development of new treatments for mood disorders.

Design, Synthesis, Structure-Activity Relationship Studies, and Three-Dimensional Quantitative Structure-Activity Relationship (3D-QSAR) Modeling of a Series of O-Biphenyl Carbamates as Dual Modulators of Dopamine D3 Receptor and Fatty Acid Amide Hydrolase

We recently reported molecules designed according to the multitarget-directed ligand paradigm to exert combined activity at human fatty acid amide hydrolase (FAAH) and dopamine receptor subtype D3 (D3R). Both targets are relevant for tackling several types of addiction (most notably nicotine addiction) and other compulsive behaviors. Here, we report an SAR exploration of a series of biphenyl-N-[4-[4-(2,3-substituted-phenyl)piperazine-1-yl]alkyl]carbamates, a novel class of molecules that had shown promising activities at the FAAH-D3R target combination in preliminary studies. We have rationalized the structural features conducive to activities at the main targets and investigated activities at two off-targets: dopamine receptor subtype D2 and endocannabinoid receptor CB1. To understand the unexpected affinity for the CB1 receptor, we devised a 3D-QSAR model, which we then prospectively validated. Compound 33 was selected for PK studies because it displayed balanced affinities for the main targets and clear selectivity over the two off-targets. 33 has good stability and oral bioavailability and can cross the blood-brain barrier.

Competing reactions of hydrophenylation and phenylation in tetraphenylantimony chloride methyl acrylate palladium chloride system

A new catalytic reaction of the competing phenylation and hydrophenylation in air of methyl acrylate with tetraphenylantimony chloride in the presence of PdCl2 (0.04 mol per 1 mol of organometallic compound) in acetonitrile at 50C for 6 h was studied. The yields of methyl cynnamate and methyl hydrocynnamate were 0.73 and 0.27 mol mol-1 respectively. The products ratio obtained depends slightly on the process duration, the Ph 4SbCl and methyl acrylate ratio, and the structure of Pd salt [PdCl2, Pd(OAc)2, Li2PdCl4], but significantly on the nature of a solvent (MeCN > DMF > THF). The use of Ph4SbCl instead of Ph4SbBr leads to decrease in the yield of methyl hydrocynnamate to 0.04 mol mol-1. In the reactions of Ph4SbX (X = F, I, OAc, O2CEt) the product is not formed at all.
