2‐Benzazepines. 7. Synthesis of pyrimido[5,4‐d][2]benzazepines [PDF]

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.

Synthesis of Benzazepine Analogues of Noscapine

Helvetica Chimica Acta, 1994
AbstractThe synthesis of benzazepine analogues of the opium alkaloid noscapine (1) is described. The benzazepines 2 and 3 were prepared starting from nornarceine ethyl ester (4; readily available from 1) in several steps. X‐Ray analysis of compound 2 revealed that it is not a diastereosisomer mixture but a racemate of the threo‐form and thus has the ...

Reaction of Vinylaziridines with Arynes: Synthesis of Benzazepines and Branched Allyl Fluorides.

Chemistry, 2020
We report the cycloaddition between vinylaziridines and arynes. Depending on the reaction conditions and the choice of the aryne precursor, the aziridinium intermediate can be trapped through two distinct mechanistic pathways.

The Synthesis of Hydroxytrifluoromethyl 3H-Benzazepines

Synthetic Communications, 1980
Abstract Recent reports have described the dopamine agonist properties of several 7,8-dihydroxy-1-phenyl-2,3,4,5-tetrahydrolH-3-benzazepines1. In an attempt to further explore the substitution pattern needed for activity, we required a method for introducing a trifluoromethyl group into the fused aromatic ring and a method for O-demethylation without ...
