Stable, single precursor for the synthesis of enantioselective rare earth metal catalysts for multi-functional asymmetric catalysis
Air and water tolerant precatalyst for Shibasaki’s rare earth metal BINOLate catalysts Problem: Asymmetric catalysis is used for synthesizing optically active or chiral materials, which form the basis for the production of numerous pharmaceuticals, natural products, fine chemicals, and biologically active compounds. Because of the cooperative...

New tandem epoxidation and oxidation reactions for intermediates in asymmetric organic synthesis
Highly enantio- and diastereoselective synthesis of epoxy alcohols from an aldehyde Problem: About half of the top-selling pharmaceuticals are single enantiomers, the precursors of which are chiral substances of high optical purity. Controlling the stereochemistry of these materials and creating stereogenic centers allows for the preparation...
