DESCRIPTION (provided by applicant): New methods for catalytic enantioselective construction of C-C bonds are fundamentally significant. In the right context, such methods can prove to be lynchpin reactions for total synthesis and they can offer new and more efficient routes to useful therapeutic agents. Along these lines, single enantiomer chiral compounds are vitally important as new materials and as medicinally relevant therapies. Indeed, one recent review article established that as of 2003, fully 50% of new drugs brought to market are single enantiomer chiral entities. Further, it was estimated that 500-1000 single enantiomer compounds are in the global drug pipeline at any one time. Clearly, our ability to prepare such chiral therapeutic agents can be enhanced substantially by the introduction of catalytic enantioselective chemical transformations that result in fundamentally new synthetic disconnections. The proposed research will extend our fruitful studies on catalytic conjugate allylation reactions to a much broader range of enantioselective cross-coupling reactions.
