Article abstract of DOI:10.1016/0957-4166(95)00365-V

A polymer-bound oxazaborolidine catalyst has been prepared and used in the enantioselective borane reduction of two model ketones. The catalyst is derived from (S)-a,a-diphenyl-2-pyrrolidinemethanol and poly-p-styrene boronic acid (1% cross-linked). After
