A method for the highly enantioselective hydrogenation of diverse seven-membered N-containing heterocycles, including 2,4-diaryl-3H-benzo[b]azepines, racemic 2,2,4-trisubstituted 2,3-dihydrobenzo[b][1,4]diazepines, and 4-substituted 1H-benzo[b][1,4]diazep

Unsubstituted and 7- or 8-substituted 4-aryl-1H-1,5-benzodiazepin-2(3H)-ones 3a-t have been synthesized by the condensation of 3-aryl-5(4H)-isoxazolones 1a-e and parent 4-substituted 1,2-benzenediamines 2a-d under acidic conditions.

N-Arylaroylacetamides and 4-aryl-1,5-benzodiazepin-4-ones were obtained by the thermolysis of 2,2-dimethyl-6-aryl-1,3-dioxin-4-ones in the presence of aromatic amines and o-phenylenediamine respectively.Investigetion of the reaction kinetics showed that the controlling stage is the generation of the aroylketenes, which takes place by a concerted -retrocycloaddition mechanism.
