摘要：
5-Amino-4-formyl pyrazole carboxylate gave facile reactions with malononitrile, hydrazine, and ketones in the presence of piperidine furnished substituted pyrazolo[3,4-b]pyridines and pyrazolo[3,4-b]quinolones. The pyridazine sulfonamides were obtained by the reaction of 5-chloro 4-formyl pyrazole carboxylate with sulfonamide derivatives.
