Palladium-Catalyzed Regio-, Enantio-, and Diastereoselective Asymmetric [3 + 2] Cycloaddition Reactions: Synthesis of Chiral Cyclopentyl Phosphonates

The palladium-catalyzed unified approach using in situ-generated Phospha-TMM species to synthesize a diverse array of chiral organophosphorus containing carbo- and heterocyclic compounds in a highly regio-, diastereo- (>20:1 dr), and enantioselective (>99% ee) fashion is being disclosed. The present protocol reveals the potential of the deprotonative phospha-TMM strategy for the synthesis of challenging five-membered carbo- and heterocycles, especially those with spirocyclic entities and quaternary asymmetric stereocenters. The choice of the robust chiral diamidophosphite ligand proved to be very crucial for the desired reactivity in the present transformation. Furthermore, the synthetic utility of the products is demonstrated by multiple transformations such as reductions, oxidations, and alkylations.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 52522-40-4, and how the biochemistry of the body works.Synthetic Route of 52522-40-4

Anticancer activity of two novel ruthenium compounds in gastric cancer cells

Aims: Ruthenium (II) complexes are promising anticancer molecules due its pharmacological properties and selectivity to cells tumor. The aim of this work was to study the cytotoxic activity, and apoptosis induction of two new ruthenium complexes on a human gastric cancer cell line. Main methods: Two ruthenium(II) complexes were synthesized: [(H2pbbzim)Ru(tpy-Ph-COOCH3)](Cl)2 (Ru-UCN1), and [(tpy)Ru(tpy-Ph-bzH)](Cl)2 (Ru-UCN3), and their anticancer capacity determined by cytotoxic assays, gene expression analysis, caspase activation and confocal microscopy. Key findings: Ru-UCN3 is more notably cytotoxic than cisplatin in human gastric cancer cells AGS at 24 h, while Ru-UCN1 is more active against gastric cancer cells than cisplatin at 48 h. The complexes induce apoptosis as shown by RT-qPCR, protease activity, and confocal microscopy. Ru-UCN1 induces the overexpression of pro-apoptotic genes at 3 and 6 h, whereas Ru-UCN3 induces overexpression of these genes at 12 and 24 h. Ru-UCN1 treatment shows a strong activation of caspases 3/7 at 24 h, which was not observed for Ru-UCN3 treatment in the same timeframe. Significance: Taken together, this data suggests that Ru-UCN1 and to a lesser extent, Ru-UCN3, may be interesting anticancer agents for gastric cancer.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 14220-64-5, help many people in the next few years.Recommanded Product: Bis(benzonitrile)palladium chloride

Oxidative cross-coupling through double transmetallation: Surprisingly high selectivity for palladium-catalyzed cross-coupling of alkylzinc and alkynylstannanes

Two different organometallic reagents now can cross-couple together with the oxidative cross-coupling strategy. Palladium catalyzed oxidative cross-couplings of alkylzinc and alkynylstannane reagents using desyl chloride as the oxidant have been explored, which produce the desired Csp-Csp3 cross-coupling product in surprisingly high selectivity and yields. The current catalytic system tolerates the presence of beta-H, and the reactions using long chain alkyl zinc reagents gave the cross-coupling product in excellent yields and selectivities. Copyright

Progress towards the Total Syntheses of Lycopodium Alkaloid, Lycopladine A

Several alkaloids derived from discrete Lycopodium species can treat Alzheimer’s disease and increase the efficiency of learning and memory in animals. Thus, Lycopodium alkaloids bearing amazingly unique hetero-polycyclic ring scaffolds persuaded scientists to look upon its biogenetic and biosynthetic pathways and to design its ambitious total syntheses. Recently, a C16N type Lycopodium alkaloid, (+)-lycopladine A; isolated from the club moss Lycopodium complanatum, showed selective but modest cytotoxicity towards murine lymphoma L1210 cells (IC50 7 mug/mL). Owing to its dense array of stereochemical features, as well as intriguing biological activity, lycopladine A has been an important synthetic target for last 12 years. An overview of the synthetic studies of lycopladine A is presented, covering literature from 2006 until March 2019.

New Pd/Pt-[60]fullerene complexes of phosphorus ylides as anticancer agents: Cytotoxic investigation and DFT calculations

Reaction of C60 with [Pd/Pt(dba)2] (dba = dibenzylideneacetone) and phosphorus ylides [Ph2P(CH2)nPPh2 = C(H)C(O)C6H4-m-OMe] (n = 1, (Y1); n = 2, (Y2)) gave the new Pd/Pt-[60]fullerene complexes. The obtained [(eta2-C60)Pd(kappa2-Y1)] (1), [(eta2-C60)Pt(kappa2-Y1)] (2), [(eta2-C60)Pd(Y2)2] (3) and [(eta2-C60)Pt(Y2)2] (4) complexes were characterized successfully by cyclic voltammetry, elemental analysis, mass spectrometry, and IR, UV-Vis and multinuclear NMR (1H, 13C and 31P) spectroscopy. The results of spectroscopic characterization revealed the different coordination modes of phosphorus ylides Y1 and Y2 as a consequence of P,C-chelation in 1 and 2 and P-coordination in 3 and 4 complexes. Theoretical studies confirmed the P,C-chelation and P-coordination behaviors of ligands Y1 and Y2, respectively. The energy decomposition analysis (EDA) showed that both C60-metal and metal-ylide bonds were more electrostatic than covalent in character. Also, the cytotoxicity activity assays have demonstrated that these complexes could effectively inhibit specific cancer cells lines.

Synthesis, characterization and theoretical studies of the heteroleptic Ruthenium(II) complexes of 2,6-bis(benzimidazolyl)pyridine

Four new Ruthenium(II) complexes [Ru(bbp)(pyterpy)](PF6)2 (1), [Ru(bbp)(bip)Cl]PF6 (2), [Ru(bbp)(biq)Cl]PF6 (3) and [Ru(bbp)(phen)Cl]PF6 (4) have been synthesized and characterized by spectroscopic techniques (IR, NMR and mass) and single crystal X-ray diffraction study of one of them (4) (where bbp = 2,6-bis(benzimidazolyl)pyridine, pyterpy = 4(4-pyridyl)terpyridine, phen = 1,10-phenanthroline, bip = 2-(benzimidazolyl)pyridine, biq = 2,2?-biquinoline). The electronic spectra of all the complexes show significant bathochromic shift of their lowest energy Metal to Ligand Charge Transfer band position with respect to [Ru(bpy)3]2+. The position of the MLCT band is modulated by the nature of the coligand, the 2,6-bis(benzimidazolyl)pyridine ligand being present in all the complexes. The change in the RuIII/II potential is also explained on the basis of the sigma/pi donor characteristic of the ligands.

Palladium-Catalyzed Decarboxylative Asymmetric Allylic Alkylation of Dihydroquinolinones

A palladium-catalyzed decarboxylative asymmetric allylic alkylation (Pd-DAAA) of benzo-fused and non-benzo-fused delta-valerolactams is disclosed. This methodology gives access to chiral lactams bearing C3-quaternary stereocenters, which are central to many natural products and biologically active compounds. The reaction proceeds via palladium-catalyzed ionization of an allyl ester, followed by carbon dioxide extrusion and recombination of the electrophilic Pd-pi-allyl complex with the in situ generated lactam enolate. This final step converts racemic allylic ester starting materials into enantiomerically enriched substituted lactams with high yield and enantiomeric excess.

Copper- versus palladium-catalyzed aromatization of 2-(methoxycarbonyl) tetralones: Synthesis of methyl 1-hydroxy-2-naphthoates

The aromatization of alpha-tetralones substituted at the beta-position by an ester group is reported using either CuI or Pd2(dba)3. In the case of using CuI (10 mol %) as catalyst and Cs2CO3 as base in dioxane, 2-(methoxycarbonyl)-alpha-tetralones are smoothly converted into the corresponding methyl 1-hydroxy-2-naphthoates at 70 C under air. Alternatively, Pd2(dba)3 (1.25 mol %) can also be used as catalyst in the presence of K3PO4 as base in toluene also at 70 C under argon. These are the most straightforward methodologies for the aromatization of these types of alpha-tetralones. CuI is the catalyst of choice due to higher efficiency, economical and practical reasons.
