【 摘 要 】

Pyrrolidino[3,4-c]pyrazoline and pyrazole derivatives were synthesized via reactions of a substituted hydrazonoyl bromide with N-arylmaleimides and active methylene reagents, respectively. Synthesized pyrazoles were reacted with hydrazine hydrate to give the corresponding pyrazolo[3,4-d]pyridazines.
