SYNTHESIS OF NATURAL PRODUCTS BEARING BENZOPYRANS MOIETY BY A DOMINO REACTIONS
An simple and general synthesis of benzopyrans was achieved by ethylenediamine diacetate-catalyzed reactions of resorcinols with a, p-unsaturated aldehydes in moderate yields by domino reactions. Also, an efficient and concise synthetic route for polycycles bearing citran, cyclol, and chalcone nuclei was developed starting from a variety of trihydroxybenzenes with substituents on the ring. These two methodologies were applied successfully to the synthesis of a number of biologically interesting natural products bearing benzopyrans.
