The present invention relates to a method of preparing a phenoxy alkanoic, alkenoic, or alkynoic acid or a salt thereof from a phenoxy containing compound via a dicarboxylate intermediate. The phenoxy alkanoic, alkenoic, and alkynoic acids and salts thereof prepared by this method are suitable for use in composition for delivering active agents via oral or other routes of administration to animals. Furthermore, the present invention relates to phenoxy dicarboxylic acids and their salts for delivering active agents, such as biologically or chemically active agents, to a target.
本发明涉及一种从含苯氧基化合物通过二
羧酸中间体制备苯氧基烷酸、烯酸或炔酸或其盐的方法。通过该方法制备的苯氧基烷酸、烯酸和炔酸及其盐适用于通过口服或其他给药途径向动物提供活性剂的组合物中。此外,本发明还涉及苯氧基二
羧酸及其盐,用于将活性剂(如
生物或
化学活性剂)输送到目标物。
