7H-Pyrido(2,3-c)- (IX, R=H) and 7H-pyrido(3,2-c)carbazole (V, R=H) have been synthesized by unambiguous routes and shown to be identical with the products resulting from the Fischer-indole ring closure followed by dehydro-genation of 6- and 7-quinolylhydrazone of cyclohexanone respectively. The cyclization of N-substituted-1,2,3,4-tetrahydro-6- and -7-quinolylhydrazone of cyclohexanone followed by
7H-吡啶并(2,3-c)- (IX, R=H) 和 7H-吡啶并(3,2-c)咔唑 (V, R=H) 已通过明确的路线合成,并显示与由 Fischer-吲哚闭环产生的产物,然后分别将环己酮的 6-和 7-喹啉腙脱氢。环己酮的 N-取代-1,2,3,4-四氢-6-和-7-喹啉腙环化,然后水解和脱氢产生线性多环系统,6H-吡啶并(3,2-b)-( VIII) 和 10H-吡啶并(2,3-b)咔唑 (IV)。现在已经制备了12种可能的吡啶并咔唑。1-苯基-5-氨基-1-苯并-三唑(X)的Skraup反应产物的结构已经确定。
