Synthesis of tetrahydro-3-benzazepines

Tetrahedron, 2012
Abstract A synthetic route toward tetrahdro-3-benzazepines 1a – f starting with 2a and 2b in modest total yield is described. The facile route was carried by Henry reaction of aldehydes 3a – e with nitroalkanes and NH 4 OAc at reflux, reduction of the resulting nitroalkenes 4a – h with LAH at rt followed by protection with K 2 CO 3 and ...

2-Benzazepines. 2. Thiazolo[5,4-d][2]benzazepines

Journal of Medicinal Chemistry, 1983
As part of a program in the area of annelated 2-benzazepines, several thiazolo[5,4-d))[2]benzazepines were prepared. Treatment of the bromo ketones 7-9 with various thio amides gave the thiazoles 10-15, which when treated with methylamine gave the title compounds.

2‐benzazepines. 10 [1]. New d‐fused 2‐benzazepines

Journal of Heterocyclic Chemistry, 1989
AbstractPyrano[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, 1983
AbstractTwo 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.

ChemInform, 1987
AbstractThe benzazepines (II), prepared from the acetylenes (I), are transformed into the isomeric esters (VI) and (VII) by consecutive bromination, dehydrobromination, and palladium‐catalyzed alkoxycarbonylation.
