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

Flash vacuum pyrolysis of a series of chiral 3-benzylthiazolidin-2-one1,1-dioxides 5, readily prepared from amino acids, results mainly in loss of SO2 to give an alkene and benzyl isocyanate, but a significant minor pathway involves unexpected loss of CO2 and water to give2-phenylthiazolines 13 and derived thiazoles.
