Abstract

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).
