A stereoselective synthesis of the versatile chiralsynthon possessing two stereogenic centers, (2S,3S)-11 (>99% ee) was achieved by using chemo-enzymatic method. The conversion of (2S,3S)-11 into the homochiral intermediates (2S,3S,4S)-25 and (2S,3S,4S)-27 corresponding to the N-terminal amino acidmoiety of nikkomycin B (1) and their application to the formal total synthesis of nikkomycin B (1) are
