Enantioselective allylation of aldehydes catalyzed by new bifunctional bisoxazoline-metal complexes
The asymmetric allylation reactions of aldehydes catalyzed by a 10 mol % bisoxazoline complex bearing a phosphine oxide moiety, which was newly designed and synthesized from l-serine, afforded the corresponding homoallylic alcohols in 48-74% yields with 3
