✦ Synopsis


A facile chemical synthesis of lanost-8-en-3 beta-ol-24-one (24-ketolanosterol) is described. This compound was found to be a potent inhibitor of 3-hydroxy-3-methylglutaryl (HMG) CoA reductase activity in cultured mouse L cells. The synthetic scheme developed in this study utilizes commercial lanosterol as a starting material and involves selective hydroboration of the C-24 double bond followed by oxidation of the carbon-boron bond at C-24 by pyridinium chlorochromate (PCC).
