A concise, protecting-group-free synthesis of the antipsychotic agent (+)-nemonapride has been achieved featuring a europium(III) trifluoromethanesulfonate (Eu(OTf)3)-catalyzed C4 selective aminolysis of a 3,4-epoxy alcohol by benzylamine and an expedient use of the resulting 4-benzylamino-1,3-diol product for constructing the pyrrolidine skeleton.
简洁,无保护基的抗精神病药(+)-尼莫那普的合成已实现,其特征在于a(III)三氟甲磺酸盐(Eu(OTf)3)催化的苄基胺对3,4-环氧醇的C4选择性氨解以及将所得的4-苄基氨基-1,3-二醇产物方便地用于构建吡咯烷骨架的用途。
