In order to avoid the thiolate addition to the carbonyl group on the oxazolidinone ring, the reaction should be carried out at a temperature lower than 0 °C. Reactions at higher temperature often provided the undesired N-acylamino alcohols 12. This tendency was notably observed in compounds possessing a bulky substituent at the Z-position.
