A stereocontrolled total synthesis of (+/-)-Acetomycin (1) is described. The acyloxy group was successfully introduced from sterically hindered alpha-side onto the gamma-butyrolactone ring.

The synthesis of (+-)-4-epi-acetomycin has been completed by the steroselective esterenolate (Carrollrearrangement of (E)-2-butenyl 2-methylacetoacetate, followed by ozonolysis and acetylation. The synthesis of (±)- acetomycin and its three diastereomers by a related route is also described.
