摘要
3-Alkyl-2-alkyliminooxazolidin-4-ones were prepared from a copper-catalyzed domino intermolecular nucleophilic addition of a-hydroxy-（or mecapto） carboxylic acid ester to carbodiimide and a followed nucleophilic substitution of the formed amino group to carboxylic acid ester. The reactions could be performed under convenient conditions and good yields were achieved in most cases.
