In order to check the corresponding compound at 31P NMR –45.4 ppm, stable pentacoordinate spirobicyclic 2-phenoxy-1,3-phenylene-dioxo-1,3,2-iminoacetoxyphosphoranes were synthesized through a new and efficient method whereby phosphorus pentachloride was displaced stepwise by catechol, N,O-bisamino acid and phenol, or catechol, phenol and N,O-bisamino acid, their 31P NMR chemical shifts are at about 31P NMR –45.0 ppm, the results showed that the compound 4 at 31P NMR –45.4 ppm was pentacoordinate phosphorane containing amino acid residue.

采用磷谱跟踪来研究上述成肽反应机理。例如在氮气保护下，0.1mmol O，O-亚苯基磷酰氯（1）和0.15mmol N，O-二苯丙氨酸（2）苯溶液加入0.6ml核磁管中，混合均匀，反应过程用磷谱检测。反应1分钟后，起始原料1(δp=19ppm)很快转变成N-磷酰苯丙氨酸的三甲基硅基酯（3）(δp=19.8ppm)，在8分钟内，3完全转变成苯丙氨酸磷烷4(δp =-45.4ppm)，同时出现环磷三酯（6）(δp=3.5ppm)。随着反应的进行，对应于化合物4的峰逐渐变小，而6逐渐变大。

Acceptable resolutions were achieved when it was applied for the separation of dipeptides including Leu-Tyr and Val-Tyr by using 1-butanol-acetic acid-water (4:1:5, V/V/V) solvent system. The proteins including cytochrome C and myoglobin, lysozyme and myoglobin, and fresh chicken egg-white proteins were well separated by 12.5% PEG1000-12.5% K2HPO4-75% water (pH 9.0) and 16% PEG 1000-12.5% K2HPO4-71.5% water (pH 8.0) system.

应用研究表明，采用正丁醇-醋酸-水(4：1：5， V/V/V)和PEG1000-磷酸钾盐-水(12.5：12.5：75， W/W/W)(pH 9.0)体系可以在较高的流动相流速和较高的固定相保留下分别实现对亮氨酸-酪氨酸和缬氨酸-酪氨酸二肽混合物以及细胞色素C与肌红蛋白、肌红蛋白与溶菌酶混合物及鸡蛋清样品中蛋白成分的成功分离。
