Total synthesis of a lanthionine peptide nisin was successfully achieved for the first time by application of new methods for preparations of dehydroalanine and lanthionine moieties, resulting in a confirmation of the proposed structure.

Synthesis of a cyclic sulfide moiety ring B in peptide antibiotic nisin was successfully achieved by desulfurization from a corresponding disulfide peptide with tris(diethylamino)phosphine. The configuration on β-carbon atom of threo-3-methyl-d-cysteineresidue in the disulfide peptide was retained through the reaction to give a desired natural threo form of methyllanthionine.
Synthesis of threo-3-methyl-d-cysteine, a moiety of β-methyllanthionine as a component of the peptide antibiotics nisin and subtilin, was achieved via (2R,3R)-1-t-butoxycarbonyl-3-methyl-2-aziridinecarboxamide derived from d-threonine. An addition of thioacetic acid or thiobenzoic acid to the aziridinecarboxamide gave S-acyl-β-mercapto-α-amino acid amide derivatives which were hydrolyzed directly or after the preformation of disulfide bond to afford the desired amino acid.
