Highly regio- and diastereoselective synthesis of homoallylic alcoholsfromallyl chlorides via organosilicon intermediates are attained. While syn homoallylic alcohols were prepared from (Z)-allyl chlorides, anti homoallylic alcohols were obtained from (E)-allyl chlorides. 1-Chloro-2,4-pentadiene reacted at the γ position of the diene system regioselectively.

that more than one Lewis basic moiety (phosphoramide) is involved in the rate- and stereochemistry-determining step of enantioselectiveallylation, bidentate chiral phosphoramides were developed. Different chiral phosphoramide moieties were connected by tethers of methylene chains of varying length. The rate and enantioselectivity of allylation with allyltrichlorosilane promoted by the bidentate phosphoramides
