چکیده
The reaction of 4-amino-5-benzylamino-3-(4-chlorophenyl)-1H-pyrazole (1) with substituted diarylidenketones (2) constitutes a convenient synthetic route to the hitherto unknown 1-benzyl-6-(4-chlorophenyl)-2-(4-R-phenyl)-4-(4-R-styryl)-2,3-dihydropyrazolo[3,4-b][1,4]diazepines (3). Structures of all products were consistent with their IR, H-NMR, C-NMR and MS spectral data. X-ray crystallography data confirm the assigned structures.
