This article describes the synthesis of a new type of chiral amino phosphine ligands from an amino naphthol starting material derived by asymmetric 1-aminoalkylation of 2-naphthol with (R)-1-phenylethylamine and benzaldehyde. The asymmetric induction properties of the ligands in the Pd(0)-catalyzed allylic substitution of 1,3-diphenylprop-2-en-1-yl acetate with dimethyl malonate has also been investigated
本文介绍了一种由氨基萘酚原料合成的新型手性氨基膦配体,该原料是2-萘酚与(R)-1-苯基乙胺和苯甲醛的不对称1-氨基烷基化反应而得。还研究了丙二酸二甲酯在Pd(0)催化的1,3-二苯基丙-2-烯-1-基乙酸酯的Pd(0)催化的烯丙基取代中的配体的不对称诱导性质,其接近定量的收率和ee最高为在优化的反应条件下获得了72.2%的产物。
