Asymmetric allylic substitution reactions between 1,3-diphenyl-2-propenyl acetate and various hetero nucleophiles were efficiently carried out using the catalysts derived from the monodentate phosphine ligands, (1R, 2S, 5R, 6S)-2,6-dimethyl-9-phenyl-9-phosphabicyclo[3.3.1] nonane and its enantiomer ((−)- and (+)-9-PBNs), and palladium (0).
使用衍生自单齿膦配体(1 R,2 S,5 R,6 S)-2,6的催化剂,可以有效地进行1,3-二苯基-2-丙烯基乙酸丙烯酯与各种杂亲核试剂之间的不对称烯丙基取代反应-二甲基-9-苯基-9-磷酸双环[3.3.1]壬烷及其对映异构体((-)-和(+)-9-PBNs)和钯(0)。
