Conclusions
-
1.
The magnitude and sign of the amplitude of the Cotton effect of the p→π transition of 17β-thiol-acetates of D-homoandrosten-17a-ones are determined by the contribution of the axial thiolacetate function in accord with the rule of octants.
-
2.
The conformational equilibrium of 17β-methyl, 17α-sulfur-substituted D-homoandrosten-17a-ones depends on the nature of the substitution in the 17α-position.
