Though enantioslectivity in the epoxidation of some substrates with soluble polymer-supported tartrates is a little lower than that with solution-phase tartrates, it is higher than enantioslectivity with insoluble polystyrene resin-supported tartrates, linear poly s and corrosslinked poly s. It is obvious that soluble polymer-supported tartrates have good catalytic activity and enantioselectivity.
