COA of Formula: C34H22NO2P. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine, is researched, Molecular C34H22NO2P, CAS is 1265884-98-7, about Stereodivergent α-Allylation of Linear Aldehydes with Dual Iridium and Amine Catalysis. Author is Krautwald, Simon; Schafroth, Michael A.; Sarlah, David; Carreira, Erick M..
We describe the fully stereodivergent, dual catalytic α-allylation of linear aldehydes. The reaction proceeds via direct iridium-catalyzed substitution of racemic allylic alcs. with enamines generated in situ. The use of an Ir(P,olefin) complex and a diarylsilyl prolinol ether as catalysts in the presence of dimethylhydrogen phosphate as the promoter proved to be crucial for achieving high enantio- and diastereoselectivity (>99% ee, up to >20:1 dr). The utility of the method is demonstrated in a concise enantioselective synthesis of the antidepressant (-)-paroxetine.
