Title: One pot multicomponent synthesis of some novel hydroxy stilbene derivatives with alpha, beta-carbonyl conjugation under microwave irradiation

Abstract: The present invention provides a method for the preparation of some novel multiconjugated 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.
