A method for synthesizing (phenylalkyloxy)phenyl-oxobutanoic acid compounds is described. The corresponding (phenylalkyloxy)acylphenyl compound is halogenated, giving the alpha haloketone. The halide is displaced by the anion of a dialkyl malonate to give a substituted malonic ester. Hydrolysis of the ester and decarboxylation of the diacid gives the desired product.
本文描述了一种合成(苯基烷氧基)苯基-氧代丁酸化合物的方法。相应的(苯基烷氧基)酰基苯化合物被卤代,生成α卤代酮。卤化物被二烷基丙二酸酯的阴离子取代,形成取代的马隆酸酯。酯的水解和二酸的脱羧反应得到所需的产物。
