Abstract

The photolysis of N, N′-dibromo-2, 5-piperazinedione in dichloromethane gave an unstable photoproduct. The alcoholysis of the photoproduct in the presence of a small amount of hydrogen bromide yielded 3, 6-diethoxy-2, 5-piperazinedione and its alcoholyzed products, ethyl diethoxyacetate, ethyl 2-(diethoxyacetylamino)-2-ethoxyacetate, N-(1-ethoxy- 1-ethoxycarbonylmethyl) oxamide, and ethyl N-(diethoxyacetyl) glycinate. The reactions of ...
