## Abstract 6β‐Iodomethyl‐19‐norcholest‐5(10)‐en‐3α‐ol (VI) was synthesized by the homoallylic rearrangement of 19‐iodocholest‐5‐en‐3α‐ol (V), which was obtained by the hydrolysis of 19‐iodocholest‐5‐en‐3α‐ol acetate derived from the displacement of cholest‐5‐ene‐3α,19‐diol 3‐acetate 19‐toluene‐p‐s
