Starting from alkyl- or aryl-substituted malonic esters prepared by various methods, 2-(methylthio)alkanoic acids are synthesized by successive treatment with sodium ethoxide and with S-methyl methanethiosulfonate, followed by alkaline hydrolysis which causes concurrent decarboxylation. Production of 2-(phenylthio)alkanoic acids is also achieved in a similar manner.
从通过各种方法制备的烷基或芳基取代的丙二酸酯开始,通过依次用乙醇钠和 S-甲基甲硫代磺酸盐处理合成 2-(甲硫基)链烷酸,然后进行碱水解,同时引起脱羧作用。2-(苯硫基)链烷酸的生产也以类似的方式实现。
