实验步骤: A mixture of 2-benzyloxycarbonylaminomalonic acid diethyl ester (Bladon, C. M. J. Chem. Soc. Perkin Trans. 1990, 1, 1151–1158) (1.237 g), iodo-2-ethylbutane (1.272 g) and lithium hydroxide (0.287 g) in N-methylpyrrolidone (8 mL) was stirred for 2 days at room temperature and then diluted with ice water. The aqueous solution was extracted with ether and the product purified by chromatography on silica gel to give 2-benzyloxycarbonylamino-2-(2-ethylbutyl)malonic acid diethyl ester (0.520 g). The aqueous solution was extracted with ether the product purified by chromatography on silica gel
