実験手順

A solution of diethyl(isocyanomethyl)phosphonate (410 μL) in diethyl ether (5 mL) was cooled to −78° C. in nitrogen atmosphere. After addition of 1.54M n-butyl lithium solution in hexane (1.7 mL) to the reaction mixture at −78° C., the temperature was raised to 0° C. and stirred for 15 minutes. To the resulting solution spiro[4.5]decane-6-one (300 mg) was added at 0° C., and the temperature was raised to room temperature under stirring. An hour thereafter, conc. hydrochloric acid (5 mL) was added to the reaction mixture at room temperature, followed by further 10 hours' stirring. The resulting solution was diluted with water and extracted with diethyl ether. The extract was dried over anhydrous magnesium sulfate, and from which the solvent was distilled off to provide the title compound in crude, unpurified form, as a colorless oily substance.
