Redox refunctionalization of steroid spiroketals. Structure correction of ritterazine M

(Equation Presented) The structure of the North spiroketal moiety of ritterazine M has been corrected from 1a to 1b. This was accomplished by comparison of published spectra of the natural product with five synthetic spiroketal-alcohols. Synthesis of thes
