Chiral titanium complex (1), prepared in situ from optically pure binaphthol and diisopropoxytitanium dihalide in the presence of molecular sieves, is shown to catalyze the addition reactions of crotylsilanes and -stannanes to glyoxylates to afford (syn)-α-hydroxy-β-methyl esters in highly scalemic forms with high diastereoselectivity.Key Words: Asymmetric catalysis; Enantiocontrol; Diastereocontrol; Allylic silane; Allylic stannane; Carbonyl-addition reaction; Carbonyl-enereaction; Glyoxylate; Binaphthol-derived titanium dihalide; Chiral titanium complex
