Abstract

Abstract Acetolysis and hydrogenolysis of 7-methanesulfonyloxy-3α, 5-cyclo-5α-cholestanes was studied. The 7β-methanesulfonyloxy derivative VI is hydrogenolyzed more readily than its 7α-isomer III. The acetolysis gives products of elimination, substitution and rearrangement with participation of the cyclopropane ring. Whereas the 7α-derivative III predominantly reacts with elimination, the 7β-derivative VI is more susceptible to the participation ...
