polymer-supported chiral N-sulfonylamino alcohols 5–8 have been prepared by suspension polymerization of enantiopure N-sulfonylamino alcohol monomers 1–4 with styrene and divinylbenzene. Polymer-supported chiralallylboronreagents were prepared from the polymeric chiral ligands. Enantioselectiveadditions of the polymer-supported allylboronreagents to aldehydes and N-(trimethylsilyl)imines have been successfully
