variously substituted on ring D, have been synthesised from 4-chloro-3-formyl-1-methylpyrrolo[3,2-c]pyridine and lithiated N,N-diethylbenzamides. These, with amines, formed the corresponding 1-alkylamino derivatives. In some cases the substitution was accompanied by the formation of polysubstituted by-products. It was found that the méthoxy groups of 7- and 10-methoxy-5-methyl-5H-pyrido[4,3-b]benz[f]indole-6
由4-氯-3-甲酰基-1合成了在环D上不同取代的1-氯-5-甲基-5 H-吡啶[4,3- b ]苯并[ f ]吲哚-6,11-醌-甲基吡咯并[3,2-c]吡啶和锂化的N,N-二乙基苯甲酰胺。这些与胺形成相应的1-烷基氨基衍生物。在某些情况下,取代伴随着多取代副产物的形成。发现7-和10-甲氧基-5-甲基-5H-吡啶并[4,3- b ]苯并[ f ]吲哚-6,11-醌的甲氧基本身被胺取代;这说明了在环D上单或多甲氧基化的某些氯代中间体取代后形成的反应产物的复杂性。
