摘要

Abstract Base-induced conjugate addition-elimination of α-arylmethyl sulfones to α- oxoketene dithioacetal 1 followed by acid-induced cyclization affords 2-phenyl-3- (methylthio)-4, 5-dihydronaphtho [1, 2-b] furans which could be converted to parent aromatized products by DDQ dehydrogenation followed by Raney-Ni dethiomethylation. The approach was found to be amenable to a variety of sulfone components. Keywords: α- ...
