| Abstract: | Reactions of 4,5-diacetoxy-1,3-diacetylimidazolidine and 2,3-diacetoxy-1,4-diacetylpiperazine with acetamide and ethyl carbamate gave 1,3-diacetyl-4,5-bis(acetylamino)imidazolidine, 1,4-diacetyl-2,3-bis(acetylamino)piperazine, 1,3-diacetyl-4,5-bis(ethoxycarbonylamino)imidazolidine, and 1,4-diacetyl-2,3-bis(ethoxycarbonylamino)piperazine, respectively. Condensation products of 4,5-diacetoxy-1,3-diacetylimidazolidine and 2,3-diacetoxy-1,4-diacetylpiperazine with urea, furazan-3,4-diamine, and 4-phenylfurazan-3-amine were isolated. |
