A series of 3-carboxylic derivatives of disubstituted 1,5-benzodiazepines (5–9) was synthesized by hetero-cyclisation from 1,2-diaminobenzene (1) with dibenzoylmethane (2) followed by bromination on position 3 and by introduction of the carboxylic group or introduction of the malonic moiety. Reduction of the hetero-cycle gave the perhydro derivative diethyl (2,4-diphenyl-1,2,4,5-tetrahydro-3H-1,5-
通过从1,2-二氨基苯(1)与二苯甲酰甲烷(2)进行杂环环化,然后在位置3溴化并引入二取代的1,5-二苯并二氮杂卓(5–9)的一系列3-羧酸衍生物羧基或丙二酸部分的引入。杂环的还原得到全氢衍生物(2,4-二苯基-1,2,4,5-四氢-3 H -1,5-苯并二氮杂-3-基)丙二酸二乙酯(9)。
