49 - 084Novel Carbonyl-Dependent Regioselective Allylation via Diethylzinc-Mediated Umpolung of π-Allylpalladium. — The allylation ofcarbonyl compounds with allyl esters such as (I) in the presence of diethylzincand catalytic Pd(0) is investigated. With benzaldehyde mainly α-allylationproducts (III) are obtained, whereas acetone and ethyl acetate yield γ-allylationproducts (VII) and (IX). — (KIMURA, M.; OGAWA, Y.; SHIMIZU, M.;SUEISHI, M.; TANAKA, S.; TAMARU, Y.; Tetrahedron Lett. 39 (1998) 38,6903-6906; Dep.
