Thiols reacted with 2-oxazolidinones in the presence of alkoxides to give β-amino sulfides in high yields. The method was applied to the synthesis of 5,6-dihydro-1,4-thiazin-3(2H)-ones.
A simple synthesis of 2-aminoethyl sulfides using a base-promoted reaction of 2-oxazolidinones with thiols is described. An application of this method to the synthesis of chiral 2-aminoethyl sulfides and sulfur-containing heterocyclic compounds is also presented. (C) 2001 Elsevier Science Ltd. All rights reserved.
