Bi(iii)-catalyzed synthesis of furocoumarins via a three component reaction of arylglyoxal monohydrates, coumarins and N-substituted anilines

Abstract

We report a Bismuth(III)triflate catalyzed novel, efficient and atom-economical one-pot three-component methodology for the synthesis of furo[3,2-c]-coumarins from arylglyoxals, 4-hydroxycoumarins and N-substituted anilines. While using N-methyl aniline, we have obtained...
