Certain 17β-aminoderivatives of 5α-steroids based on tigogenin were synthesized and their antitumor activity was studied. The structures of the synthesized
compounds were confirmed by NMR and IR spectroscopy and mass spectrometry.

17α-Amino-5ga-androst-2-ene was synthesized from epiandrosterone via formation of the tosylate followed by nucleophilic substitution
by azide and reduction with LiAlH4. The structures of the products were proved by NMR and IR spectroscopy and mass spectrometry.
