A simple, convergent, and efficient approach for the totalsynthesis of the bioactive E- and Z-isomers of cytospolide-D is described. The key features of the synthetic strategy include stereoselective methylation, regioselective epoxide opening, olefincross-metathesis, and a Yamaguchi protocol reaction for the formation of the E-olefinic geometry of the 10 membered ring; Steglich esterification and
