The title compound, C16H27O6P, was obtained from the rearrangement of the corresponding vinyl phosphate. 31P NMR experiments in solution have shown that this compound equilibrates to a mixture of three isomers in nearly equal proportions. In the crystalline state a single isomer is found which diffraction analysis identified as the enol form of the beta-keto phosphonate having R stereochemistry at atom C(8).
标题化合物C₁₆H₂₇O₆P是由相应的乙烯基磷酸酯重排得到的。溶液中的³¹P NMR实验表明,该化合物会平衡为三种几乎等比例的异构体混合物。在晶体状态下,发现了一种单一异构体,衍射分析确定其为在C(8)原子处具有R立体化学的β-酮膦酸酯的烯醇形式。
