Abstract:
A method for conducting an asymmetric reaction to a prochiral unsaturated bond contained within a compound comprising the step of contacting said compound with a supported liquid phase catalyst comprising an organometallic compound which comprises a metal and a chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl solubilized in a solvent having at least two alcohol groups,wherein each phenyl group of the 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl is at least monosulfonated, andwherein the degree to which the 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl is sulfonated is selected from the group consisting of tetrasulfonated, pentasulfonated, and hexasulfonated.
