Asymmetric allylation of aldehydes with allyltrichlorosilane promoted by chiral sulfoxides

Allylation of aldehydes with allyltrichlorosilane in the presence of sulfoxides is reported. The use of excess of (R)-methyl-p-tolylsulfoxide resulted in the formation of the corresponding homoallylic alcohols in good yields and moderate enantiomeric excesses. (C) 2003 Elsevier Ltd.
