Sequential multicomponent synthesis of α-ketoimides, from acyl chlorides, isocyanides, and silver salts of carboxylic acids

A sequential multicomponent synthesis among acyl chlorides, isocyanides, and silver salts of carboxylic acids was developed to synthesize α-ketoimides. The latter undergo an intramolecular aza-Wittig reaction to afford 2-acylquinazolinones.
