deuteration of a series of substrates, including phenylacetic acids, hydrocinnamic acid, benzylphosphonate, benzylsulfonate, and benzyl and phenyl ethyl alcohol ester, is developed by using a pyridine-based directing template. The template is installed into the substrate through a practical ester linkage. Under mild reaction conditions, a variety of phenylacetic acids containing alkyl, methoxyl, and halo substituents
钯催化的一系列底物的间选择性CH氘化反应是通过使用吡啶基导向模板开发的,这些底物包括苯乙酸,氢肉桂酸,苄基膦酸酯,苄基磺酸酯以及苄基和苯基乙醇酯。通过实用的酯键将模板安装到基材中。在温和的反应条件下,各种含有烷基,甲氧基和卤素取代基的苯乙酸在反应中是相容的,导致在间位高水平的D掺入。
