11-dihydroindolo[3,2-b]carbazoles have been obtained and plausible ways for their further modifications via the Friedel–Crafts reaction are presented. The formylation of these indolo[3,2-b]carbazoles with dichloromethyl alkyl esters catalysed by Lewis acids leads to the formation of the corresponding 2,8-diformyl derivatives. Applicability of this formylation method for modification of indolo[3,2-b]carbazoles
新型5,11-二烷基-6,12-二(噻吩-2-基)取代的5,11-二氢吲哚并[3,2- b ]咔唑已获得,并通过Friedel-Crafts反应对其进行进一步修饰的可行方法是提出了。这些吲哚[3,2- b ]咔唑与路易斯酸催化的二氯甲基烷基酯的甲酰化反应导致形成相应的2,8-二甲酰基衍生物。还证明了该甲酰化方法用于修饰在C-6和C-12带有富电子芳族取代基的吲哚[3,2- b ]咔唑的适用性。研究了2,8-二醛与活性亚甲基的Knoevenagel缩合反应。对许多新型吲哚[3,2- b]的光学和氧化还原性质的测量]咔唑已被执行。
