Abstract

A short and efficient synthetic approach has been developed for the synthesis of a variety of imidazole-fused benzodiazepinones. It is based on a Ugi multicomponent reaction strategy and uses various isocyanides to generate the key intermediates for a Mumm rearrangement process. The method is suitable for rapid syntheses of fused azaheterocycles of pharmacological interest.
