An efficient stereoselective total synthesis of (-)-galactostatin [(-)-I] from N-tert-butoxycarbonyl-2,3-isopropylidene L-serine Me ester (II) (21% overall yield) via thiazole intermediates serving as protected aldehydes is described. The parallel synthesis of the natural antipole (+)-I starts from D-serine. [on SciFinder (R)]
