- 中文摘要: Treatment of heterocyclic b-ketonitriles 1a,b with hydrazine hydrate and phenylhydrazine afforded the hydrazine derivatives 2a-d which cyclized in PPA into pyrrolo[3,4-c]pyrazoles 3a-d. Reaction of 1a,b with cyanoacetohydrazide furnished the cyanoacetyl pyrrolo[3,4-c]pyrazoles 4a,b. The hydrazine 2c reacted with b-diketone and b-ketoesters to afford pyrazolyl-pyrrolines 5-7. Also the later hydrazine reacted with some D-aldoses and aceteophenone to give the corresponding hydrazones 10-12 and hydrazine carboxamide derivatives 15a,b respectively.
