摘要： 分离出环膦二肽的几何异构体。用高分辩1HNMR结合其它光谱确定了异构体的数目,用X射线确定了它们的立体结构,发现磷上苯环与其α-碳上取代基互为顺式,六元环采用扭船式构象。

Abstract: In this paper, the geometrical isomers of cyclophosphonodipeptides were separated and the numbers of those isomers were determined by high resolution 1H NMR and other spectroscopic methods. Their structures were determined by X-ray diffraction. It was found that among the isomers the phenyl group at phosphorus atom and the substituents at its a-carbon atom were cis to each other, the cyclohexyl rings of the four products were all in twist boat form.
