A series of 1-substituted taurines, including optically active taurines, were synthesized expeditiously from epoxides via episulfidation with potassium sulfocyanate, ring-opening with dibenzylamine, followed by oxidation with performic acid, and hydrogenolysis in the presence of palladium hydroxide on carbon powder. This method was also used for the synthesis of trans-cyclic taurines.

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

N-Benzyloxycarbonyl protected u-substituted and α,β-disubstituted taurines were synthesized from olefins and epoxides via N-benzyloxycarbonylamino alcohol thioacetates as key intermediates. They are important sulfur analogues of naturally occurring amino acids and building blocks for the synthesis of u-substituted and α,β-disubstituted β-sulfonopeptides.
