Abstract

An efficient and novel, green pathway for the synthesis of naphthoxazinones applying a three component, facile one-pot condensation reaction of β-naphthol, aromatic aldehyde and urea in the presence of silica supported phosphomolybdic acid as catalyst The present procedure offers several advantage such as an excellent yield, short reaction time, simple work-up and recovery of catalyst.
