Synthesis of New Cardanol and Cardol Derivatives by Allylation and Regioselective­ Cyclocarbonylation Reactions

Abstract

Palladium acetate [Pd(OAc)₂] and 1,4-bis(diphenylphosphino)butane (dppb) catalyse cyclocarbonylation of allylic cardanol and cardol derivatives to give regioselectively 7-membered ring lactones in good yields. One of the compounds prepared exhibits excellent antioxidant properties.

Key words

allylations - carbonylations - cardanol - cardol - lactones - palladium
