Steroidal diones and trione, bicyclic diones (7 and 8) and a tricyclic dione were adsorbed on silica gel and reduced with BH3*NMe3.The carbonyl groups at C-3 of the steroids, at C-4 of 7 and at C-3 of 8 were reduced regioselectively.The FT-IR spectra of 5α- and 5β-androstane-3,17-dione adsorbed on silica gel were measured.
