An efficient method for the bismuth-catalyzed regioselective synthesis of pyranocoumarins and furocoumarins has been developed from the reaction of 4-hydroxycoumarins with propargyl alcohols. The reaction proceeds through sequential propargylation and intramolecular cyclization reactions catalyzed by bismuth(III) triflate.
