【Abstract】 Three 1-benzyl-5-alkoxylhydantoins, two of them are new compounds, have been prepared by bromination of 1-benzylhydantoin and the following substitution by alkoxyl groups. 1-Benzylhydantoin was obtained from potassium cyanate and N-benzyl glycine hydrochoride, which was derived from benzylamine and chloroacetic acid. The structure of the three compounds are confirmed by elements analysis, IR, 1H NMR.更多还原
