Heterocyclic ketene aminals 5 or 3H-1,5-benzodiazepines 4 were obtained from the reaction of benzoyl substituted ketene dithioacetals 1 with various diamines 2. The mechansim of formation of these two different products are discussed.
Solvent free, dry media supported synthesis of a series of 4-aryl/heteroaryl-2-methylthio-3H-1,5-benzodiazepines by chemo- and regioselective cyclization of substituted α-oxoketene dithioacetals with o-phenylenediamines is described. The X-ray crystallographic studies confirmed the formation of the cyclized product.

The preparation of twelve novel substituted [1,2,4]oxadiazolo[4,5-a][1,5]benzodiazepines which have potentially useful pharmacological properties; by 1.3-dipolar cycloaddition of benzonitrile oxides, generated in situ from benzohydroxamoyl chloride and triethylamine, to 1,5-benzodiazepine derivatives, is described. The structure of all products was corroborated by ir, 1H-nmr, 13C-nmr and ms.
