[Reaction: see text] A total synthesis of (+/-)-mycothiazole and a formal enantioselective approach have been achieved from 2,4-dibromothiazole. A chain extension of a homoallylic alcohol proceeding through an unsaturated sultone intermediate, generated by ring-closing metathesis, was used as a key step for the elaboration of the conjugated (Z)-dienol moiety.
