摘要：

A safe and straightforward method has been developed for the synthesis of various naphthofurans derivatives from readily available alpha,beta-unsaturated nitroalkenes and naphthols in ChCl/ZnCl2 DES media via a cascade reaction. The employed methodology is solvent-free, and ChCl/ZnCl2 DES is applied with the reaction media and catalyst dual roles. Via this reaction, 13 different naphthofuran derivatives, starting from both alpha- ad beta-naphthols have been prepared at 60 degrees C in 4 h with 86-94 % yields.
