Özet
Furan-2,3-diones la-c react with various hydrazines 2a-c under different conditions to yield the pyrazole-3-carboxylic acid-hydrazide 3a-d. Cyclocondensation reactions of la or 7 with phenylhydrazine lead to derivatives of pyrazolo[3,4-d]pyridazinones 6 and 8, respectively. The structures of all products were confirmed by elemental analysis, IR, H-1- and C-13-NMR spectroscopic measurements.
