Abstract

N-[2-(Alkylamino)-1-(2-azidophenyl)-2-oxoethyl]-N-(3-oxoprop-1-en-2-yl)amides, obtained from the Ugi reaction of a vinyliminophosphorane, 2-azidobenzaldehyde, a carboxylic acid, and an alkyl isocyanide, reacted with triphenylphosphine to give various 3-arylidene-3H-1,4-benzodiazepine in good yields via sequential Staudinger and intramolecular aza-Wittig reaction.
