Palladium-catalyzed asymmetric allylic alkylation of 1,3-diphenyl-2-propenyl acetate 18 with a dimethyl malonate–BSA–LiOAc system has been successfully carried out in the presence of new chiral aminophosphine ligands 1–5 in good yields with good enantioselectivities (up to 85% e.e.).
的1,3-二苯基-2-丙烯基乙酸酯的钯-催化的不对称烯丙基烷基化18与丙二酸二甲酯-BSA-LiOAc系统已在新的手性氨基膦的存在被成功地执行配体1 - 5以良好产率具有良好的对映选择性(高达85%ee)。
