The reactions of E-2-ferrocenylmethylidenetetralones with hydrazine proceed diastereoselectively, forming the cis isomers of diazatricycles in high yields. The studies of the anti-inflammatory activity of E-2-ferrocenylmethylidenetetralones and N-acetylindazoles showed a moderate activity in a TPA model. The structure of 2-acetyl-3-ferrocenyl-6-methoxy- 3,3a,4,5-tetrahydro-2H-benzo[g]indazole was confirmed by X-Ray diffraction analysis.
