The synthesis of a specifically ring labelled isotopomer of L-tyrosine, (L-Tyr), using a combination of chemical and enzymatic methods is reported. The tritium labelled [2′,6′]-L-Tyr has been synthesized via catalytic exchange of phenol with tritiated water in the presence of K2PtCl4, reverse acid catalysed removal of tritium from the o- and p-positions of phenol, and subsequent condensation of the
报道了使用化学和酶促方法的组合合成 L-酪氨酸 (L-Tyr) 的特定环标记同位素异构体。氚标记的 [2',6']-L-Tyr 是通过苯酚与氚化水在 K2PtCl4 存在下的催化交换、反向酸催化从苯酚的邻位和对位去除氚以及随后合成的使用来自弗氏柠檬酸杆菌的 β-酪氨酸酶将所得 [3',5-3H2]-苯酚与 S-甲基-L-半胱氨酸缩合。版权所有 © 2004 John Wiley & Sons, Ltd.
