Abstract
Various new chiral beta-sulfonamidoalcohols were prepared. The zinc complex es modified by these chiral ligands alone without the use of titanium tetra isopropoxide are effective as chiral catalysts for the addition of diethylz inc to aldehydes to afford secondary alcohols with moderate enantioselectiv ity.
