Abstract
Abstract Manwuweizic acid ( 1 ), an anticancer triterpenoid isolated from Scisandra propinqua , was synthesized from lanosterol ( 2 ) by stereoselective introduction of the (Z) α,β-unsaturated carboxylic terminal of the side chain and by abnormal Beckmann rearrangement of ring A. A new reagent of DMSO-DCC-TFA for protection of a carboxyl group as a methylthiomethyl (MTM) ester is also described.
