Poly[(S)-3-acrylamide-2,2'-dihydroxy-1,1'-binaphthyl] (poly-6) was synthesized through radical polymerization and applied in the asymmetric addition of diethylzinc to aromatic aldehydes, giving the optically active products up to 95% enantiomeric excess (ee). Besides, The poly-6 could be recycled up to six times without erosion of the enantioselectivity.

Key words: polyacrylamide, 1,1'-bi-2-naphthol, Et2Zn, aromatic aldehydes, asymmetric addition
