ONE POT MULTICOMPONENT SYNTHESIS OF SOME NOVEL HYDROXY STILBENE DERIVATIVES WITH ALPHA, BETA-CARBONYL CONJUGATION UNDER MICROWAVE IRRADIATION

摘要

The present invention provides a method for the preparation of some novel multiconj ugated 2- or 4 -hydroxy substituted stilbenes. The method provides one pot multicomponent approach wherein 3-4 step reaction sequences viz. condensation, decarboxylation and Heck coupling occur simultaneously which results in an enhanced yield of desired products and reduced reaction times
