実験手順: Combine 3-phenylpropionitrile (2.0 g, 15.25 mmol) and tetrahydrofuran (15 mL). Cool to −78° C. using a dry-ice/acetone bath. Add a solution of lithium bis(trimethylsilyl)amide (16.0 mL, 1 M in THF, 16.0 mmol). After 1 hour, add 2-(t-butyldimethylsilyloxy)ethyl iodide (4.58 g, 16.0 mmol). After the addition of 2-(t-butyldimethylsilyloxy)ethyl iodide is complete, warm slowly to ambient temperature over about 7 hours. Add water and extract twice with ethyl acetate. Dry the combined organic layers over Na2SO4, filter, and concentrate in vacuo to obtain a residue. Chromatograph the residue on silica gel eluting with 5% ethyl acetate/hexane to give the title compound: Rf=0.50 (silica gel, 10% ethyl acetate/hexane). warm slowly to ambient temperature over about 7 hours Add water and extract twice with ethyl acetate Dry the combined organic layers over Na2SO4 filter concentrate in vacuo to obtain a residue

実験手順: 920 mg sodium (40 mmole) is dissolved in 45 ml ethanol and to the ice-bath cooled solution is added 4.66 g diethyl oxalate (31.9 mmole) and 4.17 g hydrocinnamonitrile (31.9 mmole). The mixture is stirred at room temperature for 1 hour, under reflux for 3 hours, and then allowed to stand at room temperature overnight. Evaporation, acidification of the residue, and extraction with methylene chloride affords ethyl 3-cyano-2-oxo-4-phenylbutanoate in 38% yield. The compound crystallizes from petroleum ether in colorless needles; m.p. 80°-83° C. cooled solution under reflux for 3 hours to stand at room temperature overnight Evaporation, acidification of the residue, and extraction with methylene chloride
