Abstract

The selective aza-Michael addition at N1-position of indoles to 2-arylidenemalononitriles in the presence of potassium hydroxide is described. The salient features of this protocol are no transition-metal catalysts, mild conditions, high chemoselectivity, high atom economy, high yield and simple work-up procedures.
