A convenient synthesis of sidechain-modified phytosterols is achieved via a temporary masking of the stigmasterol 5,6-alkene as an epoxide. Following performance of the desired modification, the alkene is regenerated through a mild deoxygenation. The approach is applied to the syntheses of beta-sitosterol and campesterol acetate, and suggests a facile route to the (Z)-isomers of Delta(22-23) phytosterols. (C) 2010 Elsevier Inc.
