Syntheses of pterocarpenes and coumestans via regioselective cyclodehydration

A highly efficient synthetic route to pterocarpenes and coumestans is described. BCl3-mediated dehydrative cyclization of 1,3-diaryloxyacetones under mild conditions permitted regioselective ring closure to afford 3-((2-iodoaryloxy)methyl)benzo

Smooth Conversion of 3,4-Diarylcoumarins and 3,4,5-Triaryl-2(5H)-furanones to 2H-Chromene and 2,5-Dihydrofuran Derivatives with Dimethyl Sulfide-Borane Complex

Reaction of 3,4-diarylcoumarins (3,4-diaryl-2-oxo-2H-1-benzopyrans) and 3,4,5-triaryl-2(5H)-furanones with dimethyl sulfide-borane complex affords the corresponding 2H-chromenes (2H-1-benzopyrans) and 2,5-dihydrofurans in high yields. 3,4-Diaryl-2(5H)-fur
