Abstract
The synthesis of (23R)- and (23S)-5beta-cholestane-3alpha, 7alpha, 12alpha, 23, 25-pentols is described. Norcholyl aldehyde was converted into the cholestanepentols by a Reformatsky reaction with ethyl bromoacetate followed by a Grignard reaction with methylmagnesium iodide. One of the synthetic pentols, the 23S epimer was identical with a bile alcohol isolated from patients with cerebrotendinous xanthomatosis.
