摘要：A facile synthetic route for 1,2-dihydro-1-arylnaphtho[1,2-e] [1,3]oxazine-3-one/thione derivatives by one-pot three-component condensation reaction of 2-naphthol, aromatic aldehydes, and urea or thiourea in presence of snail shell as a novel, efficient, green and nontoxic catalyst, under solvent free conditions has been described. The method is associated with some attractive characteristics such as short reaction time, high yield of products, and recyclability of recovered catalyst from the reaction mixture.
