実験手順

The dimethyl 3-methyl-2-oxobutylphosphonate (b.p. 125°-135° C./11 mm.Hg; νmax 2950 cm-1, 1710 cm-1, 1470 cm-1, 1260 cm-1, 820 cm-1), used as a starting material in the above preparation, was prepared by proceeding in a similar manner to that hereinbefore described in Example 9(iv) for the preparation of dimethyl 2-oxo-4-phenylbutylphosphonate, but substituting the appropriate quantity of ethyl isobutyrate for the ethyl β-phenylpropionate used as starting material.
