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

Various substituted taurines have been synthesized expeditiously and practically in satisfactory to good yields directly from amino alcohols using a two-step, one-pot procedure, in which the amino alcohols undergo sulfuric acid esterification and subsequent sodium sulfite substitution. Treatment of amino-substituted secondary alcohols using the same procedure gave 2-substituted or 1,2-di-substituted
