Palladium-catalyzed asymmetric allylic alkylation of 1,3-diphenyl-2-propenyl acetate 7a using a dimethyl malonate–BSA–LiOAc system has been successfully carried out in the presence of new chiral aminophosphine ligands such as 4 in good yields with good enantioselectivities (up to 96% e.e.).
在新的手性氨基膦配体(例如4)的存在下,成功地进行了使用丙二酸二甲酯-BSA-LiOAc体系的钯催化1,3-二苯基-2-丙烯基乙酸7a的钯不对称烯丙基烷基化反应,并获得了良好的收率和良好的对映选择性(高达ee的96%)。
