## 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

NEARLY twenty years ago, Marker et al. (1) suggested that the true naturally occurring steroidal saponins synthesized by plants might have an open side chain moiety in which ring closure to the spiroketal structure encountered in the corresponding sapogenins is prevented by conjugation of the hydrox
