SYNTHESIS OF 7H-PYRIDO2,3-CCARBAZOLES FROM 5-BROMO-8-METHOXYQUINOLINES VIA COUPLING AND AZIDE CYCLIZATION REACTIONS

摘要

A new strategy for the synthesis of substituted 7H-pyrido2,3-ccarbazoles has been developed from substituted 5-bromoquinolines by using cross-coupling reaction with (2-aminophenyl)boric acids, followed by a regioselective azide cyclization. References: 39
