The highest enantioselectivities to date for various olefins are obtained in the osmium-catalyzed asymmetric dihydroxylation using new 9-O-aromatic dihydroquinidine and dihydroquinine ligands. A ligand structure-enantioselectivity relationship (LSER) is developed, and representative results for quinine-based ligands are reported for the first time.
