A process for easily and industrially advantageously producing a high-purity 2-aralkyl-3-acetylthiopropionic acid and a high-purity 2-aralkylpropionic acid having a leaving group in the 3-position from easily available compounds. A 2-aralkyl-1-propanol having a sulfonyloxy group or halogen atom in the 3-position is oxidized with a permanganate under acidic conditions to produce a high-purity 2-aralkylporpionic acid having sulfonyloxy or the halogen in the 3-position. This acid is reacted with a thioacetate in the presence of water to produce a high-purity 2-aralkyl-3-acetylthiopropionic acid.
一种利用容易获得的化合物生产高纯度 2-烷基-3-乙酰基硫代丙酸和 3-位有离去基团的高纯度 2-烷基丙酸的工艺。在酸性条件下,用高锰酸盐氧化在 3 位上具有磺酰氧基或卤素原子的 2-烷基-1-丙醇,生成在 3 位上具有磺酰氧基或卤素的高纯度 2-烷基硼酸。这种酸在有水的情况下与硫代乙酸酯反应,生成高纯度的 2-烷基-3-乙酰基硫代丙酸。
