Abstract
Abstract Allylation of β-diketone, β-ketoesters and methine active hydrogen compounds by allyl phenyl ethers or allyl esters with palladium/phosphine catalytic systems has been studied, and a mechanism is suggested. The use of DIOP (2, 3-O-isopropylidene-2, 3- dihydroxy-1, 4-bis (diphenylphosphino) butane) as chiral phosphine ligand produces optically active allylated compounds with up to 10% ee
