Cascade Reaction of 3-Phenacylideneoxindoles with Trimethylsilyl Cyanide: Synthesis of Furan-Fused 1,3-Benzodiazepin-2-one Derivatives

Abstract

A cascade reaction of 3-phenacylideneoxindoles with trimethylsilyl cyanide is described. This method provides an efficient route for the synthesis of furan-fused 1,3-benzodiazepin-2-one derivatives by simply refluxing a reaction mixture of various 3-phenacylideneoxindoles with trimethylsilyl cyanide in the presence of H₂O and K₂CO₃.

Key words

phenacylideneoxindoles - trimethylsilyl cyanide - cascade reaction - furobenzodiazepines
