Synthesis of N-substituted dibenzoazepine–pyridazine derivatives as potential neurologically active drugs

OpenAlex İngilizce

Syntheses of pyridazine derivatives of dibenzoazepine, starting from N-substituted-dibenzoazepines, are reported here for the first time. In the reaction sequence, N-substitute dibenzoazepine derivatives were synthesized and then, examined inverse electron demand Diels–Alder (IEDDA) reactions between N-substituted dibenzoazepine derivatives and tetrazines. While in some reactions, targeted products were obtained using phenyliodo-bis(trifluoroacetate) (PIFA), in other reactions, they were obtained directly with tetrazines which also behaved as the oxidizing agent. Structures of these compounds were fully characterized by NMR, IR, and HRMS spectroscopic techniques.
