ChemInform Abstract
A number of title steroids like (II)—(IX) are prepared as precursors for biologically active compounds and chiral ligands for metal complexation. It is found that the derivatives containing a 17α-substituent or 17-keto group possess the classical steroid conformation, whereas derivatives with a 17β-substituent adopt an atypical C-ring twist-boat and flexible D-ring conformation.
