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
本发明提供了一种制备一些新型多共轭2-或
4-羟基取代的stilbenes的方法。该方法提供了一锅多组分方法,其中包括3-4步反应序列,即缩合、脱羧和Heck偶联同时发生,从而提高了所需产品的产量,减少了反应时间。
