Reaction of 4(7)-aminobenzimidazole with ethyl 2-alkylmalonates gave the novel 4,5,6,7-tetrahydro-5-alkyl-imidazo[1,5,4-ef][1,5]benzodiazepine-4,6-diones, and the 2-alkyl-4(7)-(2′-ethoxycarbonyl)acetamido-benzimidazoles. The structure of all the products was corroborated by ir, mass spectrometry and 1H-nmr.
4(7)-氨基苯并咪唑与2-烷基丙二酸乙酯的反应得到了新颖的4,5,6,7-四氢-5-烷基-咪唑并[1,5,4- ef ] [1,5]苯并二氮杂-4,6 -二酮和2-烷基-4(7)-(2'-乙氧羰基)乙酰氨基-苯并咪唑。红外,质谱和1 H-nmr证实了所有产物的结构。
