Thermal isomerization of phosphonic α-aminoesters bearing a 4,5-carboxymethyltriazole ring in α position is described. The results are analyzed by 31P, 1H, and 13C NMR spectroscopy and X-ray crystallography. The same phenomenon is also observed in the case of carboxylic amino acids analogs. It does not occur with triazoles bearing a substituent other than carboxymethyl.
描述了在 α 位带有 4,5-羧甲基三唑环的膦酸 α-氨基酯的热异构化。结果通过 31P、1H 和 13C NMR 光谱和 X 射线晶体学分析。在羧酸氨基酸类似物的情况下也观察到相同的现象。带有羧甲基以外的取代基的三唑不会发生这种情况。
