Abstract

A simple strategy is reported for the synthesis of chiral N-protected morpholinone derivatives by a base (potassium carbonate)-mediated cyclization reaction of N-protected α-amino acids with 1,2-dibromoethane. The morpholinone derivatives are obtained in good yields and in enantiomerically pure forms.
