Thermally generated methoxycarbonylnitrene in naphthalene gave 1H-1-benzazepine and 3H-3-benzazepine derivatives, the yields of which increased with increased nitrogen pressure; formation of methyl 1-naphthyl-carbamate and the reaction path are also discussed.

A New Synthesis of 2-Benzazepines
Synthesis, 2002AlCl 3 -mediated intramolecular cyclization of N,N-bis(1H-1,2,3-benzotriazol-1-ylmethyl)-3-phenyl-1-propanamine (5) gave 2-benzotriazolylmethyl-2,3,4,5-tetrahydro-1H-2-benzazepine (6). Subsequent nuclcophilic substitution of the benzotriazolyl group in 6 with Grignard reagents, triethyl phosphite and sodium borohydride afforded 2,3,4,5-tetrahydro-1H-2 ...

Some derivatives of 1-benzazepine
Canadian Journal of Chemistry, 1969A new rearrangement of a substituted 5H-1-benzazepine-5-one is described. A new route to certain dimethyl-1-benzazepines has been developed and linked up with a known synthesis. Several new derivatives of 1-benzazepine are reported.

An Efficient Approach for the Construction of Benzazepine and Benzoxepine Derivatives
Chemistry – An Asian Journal, 2012AbstractA novel and facile synthetic protocol for the construction of benzazepine and benzoxepine derivatives through a copper(I)‐catalyzed reaction of 2‐(2‐ethynylphenyl)‐1‐tosylaziridine or 2‐(2‐ethynylphenyl)oxirane with sulfonyl azides is disclosed. A ketenimine is the key intermediate during the reaction process.

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.

Chemistry and biological activity of new 3-benzazepines
International Journal of Antimicrobial Agents, 2000This review summarizes our experiments investigating structure-activity relationships of 3-benzazepines. Three 7, 8-dihydroxy-3-benzazepines [7-9] were cytotoxic to human promyelotic leukaemia HL-60 cells. Compound [9] showed the highest cytotoxicity and the activity was twice as high as that of dopamine (DA, [11]).
