Stereoselective Synthesis of 3-(1-Cyanoalkylidene)oxindoles by Palladium-catalyzed Cyclization Reaction of 2-(Alkynyl)aryl Isocyanates with Copper(I) Cyanide
A palladium-catalyzed cyclization reaction of 2-(alkynyl)-aryl isocyanates with copper(I) cyanide provides an efficient method for the stereoselective synthesis of (Z)-configured 3-(1-cyanoalkylidene)oxindoles.
