## Abstract The acid catalyzed condensation of 4,5‐diaminopyrazoles and chalcones gave the hitherto unknown 1‐benzyl‐2,4,6‐triphenyl‐2,3‐dihydropyrazolo[3,4‐__b__][1,4]diazepines derivatives. The structure of all products was supported by ir, ^1^H and ^13^C‐nmr and mass spectra.

Friedländer condensation of 5-aminopyrazole-4-carbaldehydes 1 with formamide 2a or benzamide 2b gave pyrazolo [3,4-d]pyrimidine derivatives 3. Cyclocondensation of 1 with cyclopentanone, N-benzyl-4piperidone and 6-methoxy-1-tetralone yielded cyclopenta[b]pyrazolo[4,3-e]pyridines 4, pyrazolo[3,4-b]-[
