A synthetic approach for the totalsynthesis of salinipyrone A has been developed. Key steps involve the TiCl4-mediated vinylogousMukaiyamaaldolreaction (VMAR) of chiral ketene silyl N,O-acetal with propionaldyhyde, an aldol condensation, Witting olefination, and a cyclization. The synthesis proceeds in eight steps.
