Abstract
Polycyclic ketones react reversibly with methanol, ethanol, and isopropanol in presence of hydrogen chloride. Treatment of 5α-cholestan-3-one ( 2) in acidic methanol solution gives the crystalline dimethyl ketal ( 7). In optically active substances, the percentage of ketal formed is easily followed by RD and CD, and is a function of structural and stereochemical factors. Furthermore, the reversibility of the ketone ⇌ ketal reaction is strongly dependent on the amount of water present in the reactive medium.
