A number of 3-aryl-4-methylpyrazolobenzodiazepines and 4-aryl-2-amino-5-methyl-1,3-thiazinobenzodiazepines have been synthesized from 3-(arylmethylene)-4-methyl-1,5-benzodiazepin-2-one by cyclocondensation with hydrazine hydrate and thiourea in basic medium, respectively.All of the compounds were evaluated for their insecticidal and fungistatic activities, and the results are compared with the standard insecticide Propoxure and the standard fungicide Maneb.Some structure-activity relationships are discussed on the basis of screening data. - Keywords: Pyrazolobenzodiazepines; thiazinobenzodiazepines; insecticidal and fungistatic activities

2,3-Dihydro-4-methyl-1H-1,5-benzodiazepin-2-one (1A) and its N-alkyl derivatives (1B,C) undergo condensation with nitroso compounds as well as with a series of aromatic aldehydes to afford 3-anils (2) and 3-arylidene derivatives (3), respectively.Compounds 3 react with hydrazine hydrate in glacial acetic acid or with phenylhydrazine in pyridine to furnish the title compounds (4).The UV-visible spectra of all the compounds in ethanol have been recorded and the absorption bands assigned.
