CATALYST-FREE SYNTHESIS OF 1-PHENYLNAPHTHO[2,1-b]FURAN DERIVATIVES UNDER MICROWAVE IRRADIATION

摘要

An environmentally benign and efficient method has been developed for the synthesis of naphtho[2,1-b]furan from (E)-(2-nitrovinyl)benzene and naphthalen-2-ol in brine media under catalyst-free conditions through microwave-assisted technology. The advantages of this process are that it is catalyst-free, has an easy work-up, provides good yields, and uses brine as the solvent which is considered to be relatively environmentally benign.
