Soluble polymer-supported synthesis of benzodiazepinones

Bioorganic & Medicinal Chemistry Letters, 2002
Soluble 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 ...

A new route to 1H-1,5-benzodiazepinones

Journal of the Chemical Society, Chemical Communications, 1981
Dimethyl allene-1,3-dicarboxylates react with o-phenylenediamine to give 1H-1, 5-benzodiazepinones and not benzimidazoles; the transient enamine intermediate shows preference for a 7-exo-trig ring closure.

Synthese und Struktur substituierter 1.5‐Benzodiazepinone‐(4)

Justus Liebigs Annalen der Chemie, 1966
AbstractPiperidondicarbonsäureester reagieren mit o‐Phenylendiamin unter Ringspaltung. Dabei entstehen, neben substituierten Benzimidazolen, 2‐Alkoxycarbonylmethylen‐2.3.4.5‐tetrahydro‐1H‐1.5‐benzodiazepinone‐(4) (z. B. 1, 2). Diese bilden sich auch bei direkter Kondensation von Acetondicarbonsäureestern mit o‐Phenylendiamin oder durch Cyclisierung von

Auranthine, a new benzodiazepinone metabolite of Penicillium aurantiogriseum

Journal of the Chemical Society, Perkin Transactions 1, 1986
A novel metabolite, auranthine, has been isolated from sporing cultures of Penicillium aurantiogriseum and its structure, 6,7,7a,8-tetrahydroquinazolino[3′,2′:1,6]pyrido[2,3-b][1,4]benzodiazepine-9,16-dione comprising anthranilate and glutamine moieties, has been elucidated from spectral evidence and biosynthetic reasoning.

Attempted synthesis of 2,4‐ and 1,3‐benzodiazepinones

Journal of Heterocyclic Chemistry, 1975
AbstractThe cyclodehydration reaction performed upon α‐acylamino carboxamides is known to constitute a facile synthetic approach to five‐membered heterocyclic systems. Attempts to prepare 2,4‐ and 1,3‐benzodiazepinone derivatives (VI, XIX) of potential C.N.S. Activity using such methods, proved unsuccessful. A new triazine system (X) which was prepared

On substituent effect on the benzodiazepinone system

Computational and Theoretical Chemistry, 2012
Abstract 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

Direct liquid chromatographic separation of benzodiazepinone enantiomers

Journal of Chromatography A, 1984
Abstract The enantiomers of 46 3-substituted 5-phenyl-1,3-dihydro(2H)1,4-benzodiazepin-2-ones, diazepam (Valium®) analogues, have been chromatographically separated on chiral stationary phases derived from (R)-phenyl-glycine or (S)-leucine. Both analytical and preparative scale separations have been effected.
