A convenient one-pot synthesis of N-aryl-3-pyrrolines
摘要:
N-propargylanilines, under one-pot homologation conditions, undergo an in situ cyclisation catalysed by Cu(I) to yield 3-pyrrolines in good yield. (C) 1999 Elsevier Science Ltd. All rights reserved.

Lewis acid induced N-methyleneamine equivalents from N-(methoxymethyl)anilines or 1,3,5-triphenylhexahydro-1,3,5-triazines reacted with propargyltrimethylsilanes to give N-buta-2,3-dienylanilines, 4-methylene-1,2,3,4-tetrahydroquinolines and its oxidized product of 4-methylquinolines. These products came from branching reactions of the elimination and electrophilic aromatic substitution from the same vinylic carbocation intermediate.
