A convenient method for the stereoselective construction of angular methyl group of fuzed cyclic ethers is described. Reactions of mixed thioacetals with Me2Zn/Zn(OTf)2 afforded the corresponding methylated products in good yields. Various protective groups such as MOM ether, benzylidene acetal, TBS ether, and pivaloyl group were stable under the reaction conditions.

A total synthesis of brevenal is described. The pentacyclic ether core was constructed by the intramolecular allylation of α-acetoxy ether and subsequent ring - closing metathesis. Both of the diene side chains were introduced by Wittig olefination and a
