F. Trecourt et al., SYNTHESIS OF 7H-PYRIDO[2,3-C]CARBAZOLES FROM 5-BROMO-8-METHOXYQUINOLINES VIA COUPLING AND AZIDE CYCLIZATION REACTIONS, Journal of heterocyclic chemistry, 32(4), 1995, pp. 1261-1267
A new strategy for the synthesis of substituted 7H-pyrido[2,3-c]carbaz
oles has been developed from substituted 5-bromoquinolines by using cr
oss-coupling reaction with (2-aminophenyl)boric acids, followed by a r
egioselective azide cyclization.
