A facile and efficient deuteration method of phenylalanine derivatives using a Pd/C-H2-D2O system has been developed. Selective deuteration at the β-position of phenylalanine derivatives occurred using Pd/C as a catalyst with high deuterium efficiency without racemization at 110 °C. Also, the α-position was deuterated at higher temperature.
开发了一种简单高效的苯丙氨酸衍生物的氘化方法,采用 Pd/C-H2-D2O 系统。在 110 °C 条件下,使用 Pd/C 作为催化剂,苯丙氨酸衍生物的β位选择性氘化发生,且氘效率高,未出现消旋化。此外,在更高温度下,α位也进行了氘化。
