The three-component reaction of 4-phenyl-, p-methoxyphenyl-, and thienylpyrrolo[1,2-a][1,4]benzo-diazepines with methyl propiolate and indole in dichloromethane proceeds through opening of the diazepine ring. The major transformation products isolated are substituted pyrroles, namely, 1-(2-aminomethylphenyl)-5-(arylmethyl)-2-(indol-1(3)-yl)pyrroles and 1-(2-aminomethylphenyl)-2-aryl-(indol-3-yl)-methylpyrroles
4-二苯基,对甲氧基苯基和噻吩并吡咯并[1,2- a ] [1,4]苯并二氮杂卓与丙酸甲酯和吲哚在二氯甲烷中的三组分反应通过打开二氮杂pine环而进行。分离的主要转化产物是取代的吡咯,即1-(2-氨基甲基苯基)-5-(芳基甲基)-2-(吲哚-1(3)-基)吡咯和1-(2-氨基甲基苯基)-2-芳基-(吲哚-3-基)-甲基吡咯。
