2‐benzazepines. 10 [1]. New d‐fused 2‐benzazepines
Journal of Heterocyclic Chemistry, 1989AbstractPyrano[3,2‐d][2]benzazepines were synthesized by reaction of the beta‐dimethylamino unsaturated ketone 1 with malonic ester or the anion of t‐butyl acetate. Conversion of the pyrano derivative to the pyrido[3,2‐d]‐[2]benzazepine was achieved in low yield.

2‐Benzazepines. 7. Synthesis of pyrimido[5,4‐d][2]benzazepines
Journal of Heterocyclic Chemistry, 1983AbstractTwo novel syntheses of pyrimido[5,4‐d][2]benzazepines are described. The first synthesis started with 3‐phenylphthalide which in three steps was converted to a functionalized pyrimidine which was cyclized to give the 2‐benzazepine ring system.

Electrochemical oxidation of 2,5-dihydro-1h-1-benzazepines : Synthesis of 5H-1-benzazepines
Tetrahedron, 1995Abstract Formation of 5H-1-benzazepines was observed after electrochemical oxidation of the title compounds in a flow cell at a graphite felt anode and in acetic buffer. In basic medium, coupling reaction also occurs leading to [2,5-dihydro-1H-1-benzazepin-1-yl]-5H-1-benzazepines. Oxidation mechanisms are discussed.

2,4-Diphenyl-3H-1-benzazepine is deprotonated with either LDA or KHMDS. The resulting anion is alkylated with alkyl halides or MeOTs, giving either products of alkylation at C3, or at N, or a mixture of both. The regioselectivity depends on the base, presence of the complexing agent HMPA, and the leaving group of the alkylating agent.
