  Syntheses and ultraviolet absorption of aza-steroids

  摘要：

  A series of aza-steroids was synthesized containing chromophoric groups, such as a, beta-unsaturated ketones and doubly unsaturated conjugated and monoconjugated heteroannular dienones with the heteroatom in the D ring at the 20 and 17a positions. The effect of an appositely placed electronegative center in these molecules upon their ultraviolet absorptions was studied. In order to obtain a basis for the observed spectral changes, the corresponding carbocyclic compounds were also synthesized. The maximum absorptions of the aza-steroids were hypsochromically shifted relative to the carbocyclic compounds in all cases (n=8). The displacement caused by the electronegative center on absorption maximum of the chromophores is, however, highly dependent on its location within the molecules.
