N2 - The rearrangement of 5-cholestene to (20ξ)-13(17)-diacholestenes, separation of C-20 epimers, and further reduction provided an unambiguous synthesis of the biomarkers (20R)- and (20S)-13β, 17α(H)-diacholestanes. Repetition of this sequence using (24R)-5-campestene or (24R)-5-stigmastene provided the analogous C28 and C29 diasteranes.
