for the diastereoselective preparation of 4- and 4,5-substituted oxazolidinones from Morita–Baylis–Hillman adducts. The strategy is based on an intramolecular cyclization involving a nucleophilicattack of an alkoxide ion to the carbonyl group of a carbamate. The latter is prepared from a Curtius rearrangement having Morita–Baylis–Hillman adduct as substrate. The oxazolidinones were prepared in six
