Variable temperature n.m.r. behaviour of 1,5‐benzodiazepinones and 1,5‐benzodiazepinthiones
Organic Magnetic Resonance, 1976 AbstractThe n.m.r. variable temperature behaviour of the 7‐membered ring in 1,3‐dihydro‐2H‐1,5‐benzodiazepin‐2‐one derivatives and in the corresponding 2‐thiones has been investigated. The results indicate that the ring inversion barrier is higher in the thiones and dependent on substituents bonded at N‐1.

Soluble polymer-supported synthesis of benzodiazepinones
Bioorganic & Medicinal Chemistry Letters, 2002Soluble polymer-supported synthetic method provides a highly efficient route for the construction of biologically important 1,5-benzodiazepin-2-ones. A library of N-substituted benzodiazepinones can be readily assembled utilizing S(N)Ar reaction, reduction of nitro group and one-pot cyclization following N-alkylation as the key step in the synthesis ...

On substituent effect on the benzodiazepinone system
Computational and Theoretical Chemistry, 2012Abstract Tautomerism, aromaticity, and electron density at ring critical points of substituted benzodiazepinones, composed of condensed 6- and 7-membered rings (7-substituted 1,3-dihydro-benzo[e][1,4]diazepin-2-ones), were studied at the B3LYP/6-31G ∗∗ level. We found that in the gas phase and in water, the N1H tautomers are more stable than the N4H
