proposed for the preparation of N-(2-aminophenyl)isoindoles by the reaction of o-(bromomethyl)benzophenones with 1,2-phenylenediamines. The reaction of N-(2-aminophenyl)isoindoles with Ac2O leads to 1,N-diacetyl- or 1,N,N-triacetyl derivatives, whereas heating with formic acid or diethyl oxalate leads to cyclization with the formation of 11-arylisoindolo[2,1-a]quinoxaline derivatives.

提出了一种通过邻-(溴甲基)二苯甲酮与1,2-苯二胺反应制备N-(2-氨基苯基)异吲哚的新方法。N-(2-氨基苯基)异吲哚与Ac 2 O的反应生成1,N-二乙酰基或1,N,N-三乙酰基衍生物,而与甲酸或草酸二乙酯加热会导致环化反应,形成11-芳基异吲哚并[2,1-a]喹喔啉衍生物。研究了11-芳基异吲哚并[2,1-a]喹喔啉系列中的盐形成。
