Abstract

The preparation and characterization of a soluble copolymer P1 between styrene, divinylbenzene (DVB) and the enantiomerically pure salicylaldimine ligand 3c is described. The Lewis acid prepared from this macromolecular chiral ligand and Ti(OiPr)4 has been used in the catalytic Mukaiyama reaction to afford benzyl (R)-3-hydroxy-3-phenylpropanoate 7.
