Taurine and structurally diverse substituted taurines have been synthesized by peroxyformic acid oxidation of the thiazolidine-2-thione intermediates generated from vicinal amino alcohols or aziridines and carbon disulfide. Thestereochemistry and mechanisms of the reactions are disscussed. The method is a salt-free and versatile route, convenient in terms of purification, and can be used to synthesize

The reactions of vic-iodoisothiocyanates with some sulphur nucleophiles to form either 2-sulphur-substituted 2-thiazolines or thiazolidine-2-thiones are reported. The thiazolidine-2-thione (10) is an effective sulphur-transfer agent for the conversion of oxirans into the corresponding thiirans.
