Palladium-catalyzed asymmetric allylic alkylation of 1,3-diphenyl-2-propenyl acetate (4) with a dimethyl malonate-BSA-LiOAc system and its derivatives has been successfully carried out in the presence of a new chiral hydrazone ligands such as 2-(diphenylphosphino)benzaldehyde SAMP hydrazone (DPPBA-SAMP) (3a) in high yields with high enantioselectives.
在新型手性腙配体如2-(二苯基膦基)苯甲醛SAMP腙（DPPBA-SAMP）（3a）存在下，钯催化乙酸1,3-二苯基-2-丙烯酯（4）与丙二酸二甲酯-BSA-LiOAc体系及其衍生物的不对称烯丙基烷基化反应已成功实现，产率高且对映选择性高。
