Chiral 3-methylthio alcohols have been synthesized through a known intramolecular sulfur transfer reaction that has been carried out in di- and trisubstituted alpha,beta-unsaturated N-enoyl oxazolidinethiones as substrates, giving rise to synlanti-diastereomers. The anti-diastereomer is favored and obtained via a highly diastereo-selective protonation step (c) 2005 Elsevier Ltd. All rights reserved.
