The regioselectivity of dehydrobenzene reaction with 10-substituted benzo[b][1,6]naphthyridines was found to depend on electronic effects due to the C-10 substituent. Stevens rearrangement of 10-cyano-substituted naphthyridines produced 1-alkyl-2-phenyltetrahydrobenzonaphthyridines. 10-Carbamoyl-substituted naphthyridines underwent Hoffman cleavage of the tetrahydropyridine ring, giving 3-phenylally
发现由于C-10取代基,与10-取代的苯并[ b ] [1,6]萘吡啶的脱氢苯反应的区域选择性取决于电子效应。10-氰基取代的萘啶的史蒂文斯重排产生了1-烷基-2-苯基四氢苯并萘啶。10-氨基甲酰基取代的萘啶经四氢吡啶环的霍夫曼裂解,得到3-苯基烯丙基氨基甲基-2-乙烯基喹啉。
