چکیده

An efficient green procedure for the preparation of aryl naphthoxazinones, applying a three-component one-pot condensation reaction of 2-naphthol, aromatic aldehyde and urea in the presence of HA zeolite under heating conditions in dimethyl sulfoxide has been developed. The present procedure offers several advantages such as short reaction time, simple workup and moderate to high yields, recovery and reusability of the catalyst
