Abstract
We have previously studied the use of enantiomeric chiral reducing agents in solution to control the direction of the hydrogenation of the keto group of estrone and estrone-3-methyl ether [1]. The complex catalysts chiral hydrosilane-rhodium-( +)- or (-)-DIOP or (+)- or (-)-BINAP allowed different stereoselectivities in the formation of the 17α- and 17β-alcohols.
