  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.

• Facile synthesis of various substituted taurines, especially syn- and anti-1,2-disubstituted taurines, from nitroolefins

  Taurine and substituted taurines present a group of important structural elements in many natural products. Various substituted taurines, including 1- and 2-substituted, 1,1-, syn-1,2-, and anti-1,2-disubstituted taurines, were synthesized from the corresponding nitroolefins via Michael addition with thioacetic acid, oxidation with peroxyformic acid, and the catalytic hydrogenation under the catalysis of palladium on carbon or platinum dioxide. It is a general, versatile, and salt-free method for the preparation of substituted taurines, especially for syn- and anti-1,2-disubstituted taurines and some taurines with more bulky substituents. The stereostructures of both syn- and anti-1,2-disubstituted taurines were deduced from the nitroalkyl thioacetates in the Michael addition, which were identified via the Karplus equation analysis and computational analysis, and finally confirmed by the XRD single crystal analysis. The diastereoselectivity in the Michael addition was rationalized with the Cram rule. (C) 2012 Elsevier Ltd. All rights reserved.
