Copper‐impregnated magnesium‐lanthanum mixed oxide [Cu(II)/Mg−La] was used as catalyst in synthesis of homoallylic alcohols from aldehydes and ketones using allyltributylstannane as the allylating source. The present protocol provides a great application potential for the synthesis of corresponding allyl alcohols with excellent yields and selectivity. The catalyst exhibits broad functional group compatibility
Enantioselective reduction of heteroaromatic β,γ-unsaturated ketones was found to be an efficient and convenient alternative to the allylboration of corresponding aldehydes. This new method was used for the formal asymmetric synthesis of SIB-1508Y 2.

A facile synthesis of homoallylic alcohols is achieved by the allylation of aldehydes with allylic metal reagents or allyl halides using copper fluorapatite (CuFAP) as catalyst under mild reaction conditions. A variety of aldehydes were converted to the corresponding homoallylic alchohols, demonstrating the versatility of the reaction.
