ENANTIOSELECTIVE SYNTHESIS OF SEC-ALLYLALCOHOLS BY CATALYTIC ASYMMETRIC ADDITION OF DIVINYLZINC TO ALDEHYDES.

Article abstract of DOI:10.1016/S0040-4039(00)80834-5

Readily available chiral tridentate ligand 8 catalyzes the highly Si-face selective addition of diethyl-, di-n-propylzinc and, more significantly, of divinylzinc to aromatic and aliphatic aldehydes whereas bidentate ligands 11 and 12 exert a topologically reversed catalytic bias.
