The asymmetric synthesis of a series of 3-thiazoline carboxylates, 2, was effected by MnO2 oxidation of the corresponding cis/trans thiazolidines, 1. The stereochemistry of the oxidation reaction was studied using NMR and chiral GC analyses. Compounds 2 were obtained with enantiomeric excesses (e.e.s) in the range of 40–100%.
