Application of Photoamination to Synthesis of Benzylisoquinolines, Aporphins, and Isopavines
摘要:
The preparation of benzylisoquinolines, isopavines, and aporphines was performed by the photoamination of stilbene, p-methoxystilbene, and phenanthrene with amino alcohols, aminoacetal, allylamine in the presence of dicyanobenzene followed by the cyclization with BF3 or CF3SO3H.

An array of alpha-branched amines has been prepared by using an expedient three-component Mannich-type reaction among organic halides, aldehyde derivatives, and amines. The experimental procedure, which is characterized by its simplicity, employs zinc dust for the in situ generation of organozinc reagents. We show that this Barbier-like protocol constitutes a useful entry to diaryl-methylamines, 1,2-diarylethylamines, alpha- or beta-amino esters, benzylamines, and beta-arylethylamines.

potent organic pyrimidopteridine photoredox catalyst (E*[PrPPT*/PrPPT·–] = +2.10 V vs SCE in MeCN), the photo-mediated hydroamination of stilbenes was enabled using unprotected, primary aliphatic, allylic, benzylic amines for the synthesis of various α-phenyl phenethylamine derivatives. Notably, the stereogenic center of α-chiral amines was fully preserved. Both starting materials serve as competent quenching
