摘要

研究了手性带金属冠的La(III)-Cu(II) - l -苯丙氨酸-氢邻酸盐配体与外消旋乳酸的络合作用。x -射线衍射分析显示固态的l -乳酸双齿螯合形成对映不纯晶体。因此，l -苯丙氨酸氢ximate La(III)-Cu(II)金属冠对l型乳酸具有很强的配位性，提供了目标化合物的手性分离。

Bidentate Lactate Binding to La(III)-Cu(II) Metallacrown with L-Phenylalaninehydroximate Ligands: the Chiral Separation of L-Lactate

The chiral La(III)-Cu(II) metallacrown bearing L-phenylalaninehydroximate ligands was probed for complexation towards racemic lactate. X-Ray diffraction analysis revealed the bidentate chelation of L-lactate in the solid state to form enantiopure crystals. L-Phenylalaninehydroximate La(III)-Cu(II) metallacrown showed, therefore, a strong preference for coordination of the L-type lactate providing the chiral separation of the target compound.
