Synthesis of Benzazepine Analogues of Noscapine
Helvetica Chimica Acta, 1994AbstractThe 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 ...

The Synthesis of Hydroxytrifluoromethyl 3H-Benzazepines
Synthetic Communications, 1980Abstract 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 ...

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 ...

Publisher Summary This chapter discusses 1-, 2-, and 3-Benzazepines. Ring closure with the formation of a carbon-nitrogen bond, of the types A-E shown in the chapter, has been used to synthesize derivatives of 1-, 2-, and 3-benzazepines, with aminocarboxylic acids, amino halides, dihalides, dinitriles, dicarboxylic acids, and carboxylic acid diamides
