Some pyrrolo[2,1-c][1,4]benzodiazepines having a chain of two carbon atoms, as it is found in antibiotic tomaymycin, were prepared. The first reaction was the C-acetylation of 1-(2-nitrobenzoyl)-Δ4-pyrroline-2,2-dicarboxylic acid diethyl ester; successive transformations of the acetyl group and cyclization gave the proposed structures.
制备了一些在抗生素托马霉素中发现的具有两个碳原子链的吡咯并[2,1- c ] [1,4]苯并二氮杂s。第一反应是1-(2-硝基苯甲酰基)的C-乙酰-Δ 4吡咯啉-2,2-二羧酸二乙酯; 乙酰基的连续转化和环化产生了所提出的结构。
