The oxidation of 3,7-disubstituted hexahydroindazoles with potassium hexacyanoferrate(III) afforded previously unknown tetrahydro-2H-indazole derivatives. A novel ring contraction reaction leading to 2,3-diazaspiro[4.4]non-3-en-1-one derivatives was discovered. The product structure was proved by NMR spectroscopy, mass spectrometry, and X-ray analysis.

2-Acetyl-3-aryl-7-arylmethylene-3,4,5,6,7,9-hexahydro-2H-indazoles enter into the ene reaction with 4-phenyl-3H-1,2,4-triazole-3,5(4H)-dione to give the corresponding monoene adducts. Under analogous conditions, 3-aryl-7-arymethylene-2-methyl-3,4,5,6,7,9-hexahydro-2H-indazoles give mono- and polyaddition products. The structures of compounds obtained were established using UV, IR, 1H and 13C NMR spectroscopy and X-ray diffraction analysis.
