Abstract: Compound (2) was synthesized through condensation of ethyl N-isoproyl-N-(2-car-boethoxy benzyDglycinate. Compound (1) was obtained from the hydrolysis and decarboxylation of (2) in the presence of 18% HCl.Derivatives of (1), (3a-6e) were produced by condensation of (1) with benzaldehyde and p-substituted benzaldehyde, phenylhydrazines and oxime or (4) with benzoyl chlorides, respectively. Benzodiazepinone (7) was prepared by Beckmann rearrangement of (4) or reaction of (1) with NaN3. Pyrazolo-isoquinolones(8a-d) were synthesized through the condensation of (2) with hydrazine or substituted hydrazine, respectively. The structures of 20 new compounds have been confirmed by element analysis, IR and 1HNMR.

Key words: Isoquinolone, Pyrazole, Benzodiazepinone
