詳細

アプリケーション

Developed by Albrecht Berkessel′s lab, this is the first catalyst system that allows catalytic enantioselective epoxidation of non-conjugated terminal double bonds with hydrogen peroxide as the oxidant. Eradicating multiple steps and kinetic resolution, this chiral ligand, when used with Ti(OiPr)₄ provides a one-step route to enantiopure epoxides that are important intermediates for synthesis of bioactive compounds. Catalyst is recyclable under some conditions. For best results, pentafluorobenzoic acid (P5360) or tetra-n-butylammonium hydrogensulfate (155837) is recommended as a co-catalyst.
