## Abstract Oxidation of 5α‐cholest‐8(14)‐ene‐3β,7α,15α‐triol with silver carbonate‐celite gave 5α‐cholest‐8(14)‐ene‐7α,15α‐diol‐3‐one in 88% yield. Treatment of the latter compound with tritiated water under basic conditions gave a labeled product which was reduced with lithium tri‐__tert__‐butoxy
