Abstract

A free bis-cinchona alkaloid derivative ligand was prepared by a simple synthetic manipulation.
With ligand/olefin mole ratio of 1%, the asymmetric dihydroxylation reactions of six olefins
proceeded smoothly to give the chiral vicinal diols in high chemical yields and optical yields.
The ligand itself could be recovered quantitatively by a simple operation and reused five times
without loss of enantioselectivity.

Keywords

asymmetric dihydroxylation; bis-cinchona alkaloid derivative; recoverable and reusable ligand
