Environmentally Benign one Pot Synthesis of 1,2-Dihydro-1-(4-Chlorophenyl) -3H-Naphth-(1,2-e) (1,3)-Oxazin-3-one Under Microwave Irradiations.

摘要

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 pnosphomolybdic acid as catalyst The present procedure offers several advantage such as an excellent yield, short reaction time, simple work-up and recovery of catalyst
