Abstract

A concise assembly of the 1,3-benzodiazepine core from A 3 -coupling-derived propargylamines and ortho-bromophenylisocyanates is described. The developed synthetic sequence involves the addition of propargylamine to isocyanate followed by palladium-catalyzed intramolecular alkyne hydroarylation that could be accomplished in a stepwise or one-pot manner.
