## Abstract (25S)–5α‐cholestane‐3β, 26‐diol [2,4,2′,4′–^3^H~4~] was synthesized by hydrogenation of neotigogenin acetate 2, followed by acetylation to (25S)‐5α‐furostane‐3β, 26‐diol diacetate 5; this was oxidized to (25S)–16–22‐dioxo‐5α‐cholestane‐3β, 26‐diol diacetate 6. Clemmensen reduction of th
