title: An expedient route to imidazo[1,4]diazepin-7-ones via a post-Ugi gold-catalyzed heteroannulation.
abstract: A novel diversity-oriented post-Ugi/gold(I)-catalyzed heteroannulation process for the synthesis of imidazo[1,4]diazepin-7-ones is elaborated. The scope and limitations of the protocol are discussed.
