Abstract

Abstract Benzopyran derivatives were synthesized in good yields by the reactions of tris [2- (chloromethyl) phenyl] bismuth diacetate and 2-(halomethyl) aryllead triacetates with phenols and naturally occurring 4-hydroxycoumarins in the presence of bases according to a three-step one-pot procedure.
