Regio- and Stereoselective Synthesis of Functionalized Dihydropyridines, Pyridines, and 2H-Pyrans: Heck Coupling of Monocyclopropanated Heterocycles

A palladium-catalyzed coupling between aryl halides and monocyclopropanated pyrroles or furans has been developed, leading to valuable six-membered N- and O-heterocycles. As the key step, a selective cleavage of the non-activated endocyclic C?C bond of the 2-heterobicyclo-[3.1.0]hexane framework is achieved. The developed method offers access to highly functionalized piperidines, pyridines, and pyrans that are challenging to access by traditional methods.

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.Recommanded Product: Pd2(DBA)3, you can also check out more blogs about52409-22-0

Reactions of Methylenecyclopropanes, V. Palladium(0)-catalyzed Codimerisation of Methylenecylopropane with Methyl Acrylates and 1,2-Ethylenedicarbonic Esters

Triorganylphosphane-modified palladium(0) compounds catalyze the codimerisation of methylenecyclopropane (1) with methyl acrylate, methyl trans-crotonate or trans-cinnamate to give the methylenecyclopentanecarboxylic esters 3, 4, 5; diethyl fumarate or dimethyl maleate and 1 lead to the methylenecyclopentanedicarbonic esters 12.With diethyl maleate besides cis/trans-12b also oligomers containing two mols of 1 and one (cis/trans-14) or two mols of the diester (cis/trans-15) are formed.

Pinpoint-fluorinated phenanthrene synthesis based on C-F bond activation of difluoroalkenes Dedicated to Prof. Veronique Gouverneur on the occasion of her receipt of the 2014 ACS Award for Creative Work in Fluorine Chemistry.

Treatment with a cationic palladium(II) catalyst promoted the Friedel-Crafts-type cyclization of 1,1-difluoro-1-alkenes bearing a biphenyl skeleton to afford regioselectively fluorinated (pinpoint-fluorinated) phenanthrenes via C-F bond activation. The obtained pinpoint-fluorinated phenanthrenes were observed to be organized by pi-pi and C-H?F interactions to exhibit columnar and layer structures in the solid state.

A comparative study of bithiophene and thienothiophene based polymers for organic field-effect transistor applications

2,2?-Bithiophene and thieno[3,2-b]thiophene were polymerized separately with bis(2,3-dialkylthienyl)benzo[1,2-b:4,5-b?]dithiophene by Stille coupling reactions to afford new conjugated polymer PBDTT-2T and PBDTT-TT. The polymers showed band gaps about 1.90?eV and the highest occupied molecular orbital (HOMO) energy levels below ?5.20?eV. The PBDTT-2T and PBDTT-TT achieved hole mobilities of 0.035 and 0.008?cm2?V?1?s?1 in top-contact/bottom-gate organic field-effect transistor devices. The investigation of thin-film microstructures and morphologies showed that PBDTT-2T thin films had more uniform surface and better crystalline quality than PBDTT-TT did.

Nickel(II) dibromide complexes bearing bis(benzimidazolyl)amine and Bis(benzimidazolyl)pyridine ligands for ethylene oligomerizations

A series of bis(benzimidazolyl)amine and bis(benzimidazolyl)pyridine ligands and their respective nickel(II) dibromide complexes were synthesized and fully characterized. After activation of the nickel complexes with ethylaluminum sesquichloride showed productivity in excess of 106 (g-oligomer)(mol-Ni)-1h-1bar-1 towards ethylene oligomerization, producing butenes as major products. The bis(benzimidazolyl) pyridine nickel complexes showed higher activity and dimerization selectivity than corresponding bis(benzimidazolyl)amine nickel complexes.

Novel Di- and Trinuclear Palladium Complexes Supported by N,N?-Diphosphanyl NHC Ligands and N,N?-Diphosphanylimidazolium Palladium, Gold, and Mixed-Metal Copper-Gold Complexes

The reaction of the trinuclear complex [Ag3(mu3-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)3 (Ag3; PCNHCP = N,N?-bis(di-tert-butylphosphanyl)imidazol-2-ylidene) with [Pd(dba)2] afforded the trinuclear palladium complex [Pd3(mu3-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)2 (Pd3) and the dinuclear palladium(I) complex [Pd2(mu2-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)2 (Pd2). The assignment of the oxidation state of the metals in the mixed-valence Pd3 chain as Pd0-PdII-Pd0 was based on the reactivity of the complex with 2,6-dimethylphenyl isocyanide and density functional theory calculations. Reaction of PCNHCP with [PdMe2(tmeda)] afforded the palladium(II) complex [PdMe2(PCNHCP,kappaP,kappaCNHC)] (Pd-Me2), with PCNHCP acting as a bidentate ligand. The reaction of PCNHCP with [Pd(dba)2] led to a dinuclear palladium(0) complex [Pd2(mu2-PCNHCP,kappaP,kappaCNHC,kappaP)](dba) (Pd2-dba); attempted replacement of the remaining dba by PCNHCP failed. The imidazolium triflate PCHP, precursor to PCNHCP, was reacted with [Pd2(dba)3]¡¤CHCl3 to give the (2 + 2) metalla-mesocyclic cationic palladium(0) complex [Pd2(mu2-PCHP,kappaP,kappaP)2] (PCHP-Pd2), which resisted further deprotonation of the imidazolium cation. In contrast, PCHP reacted with [AuCl(tht)] to give [Au2Cl2(mu2-PCHP,kappaP,kappaP)] (PCHP-Au2), in which one Au-Cl moiety is bound to each P donor. Further reaction of PCHP-Au2 with [Au{N(SiMe3)2}(PPh3)] afforded a mixture of the trinuclear [Au3(mu3-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)3 (Au3) and [AuCl(PPh3)], while reaction with [CuMes]5, where Mes = 2,4,6-trimethylphenyl, resulted in a novel, centrosymmetric, heterometallic complex [Au2Mes2(Cu4Cl4)(PCHP,kappaP,kappaP)2] (PCHP-AuCu) featuring a new PCHP-AuMes metalloligand bridging a Cu¡¤¡¤¡¤Cu diagonal of a Cu4Cl4 cubane via the P and AuMes functionalities.

PROGNOSTIC BIOMARKERS FOR TTK INHIBITOR CHEMOTHERAPY

The present invention provides a method for identifying a tumor – in a human individual or in an animal – that is susceptible to treatment with a TTK inhibitor, said method comprising: a] providing a sample of a tumor; b] determining the presence of a mutated CTNNB1 gene in said tumor sample, wherein said mutation is located in exon 3 of CTNNB1 and whereby the presence of a mutated CTNNB1 gene indicates that the tumor is susceptible to treatment with a TTK inhibitor. In an alternative aspect, step b] of the above defined method is replaced by the step of determining the presence of a mutated CTNNB1 protein in said tumor sample, wherein said mutation is located in exon 3 of CTNNB1 and whereby the presence of a mutated CTNNB1 protein indicates that the tumor is susceptible to treatment with a TTK inhibitor. In a further alternative, step b] comprises determining an altered expression of a CTNNB1 regulated gene, whereby an altered expression of a CTNNB1 regulated gene indicates that the tumor is susceptible to treatment with a TTK inhibitor.
