By applying the Hantzsch thiazole procedure, the synthesis of bithiazole derivatives (2 and (±)-3) corresponding to degradation products of myxothiazol was achieved. Optically active (S)-3 (87-88% ee) and its analog (S)-16(91% ee) were obtained through enantioselective hydrolysis of the corresponding acetates ((±)-18, (±)-20 and (±)-21) using lipase in water-saturated organic solvent.
