The two major metabolites of ibuprofen, 2-[4-(2-carboxypropyl)phenyl]propionic acid and 2-[4-(2-methyl-2-hydroxypropyl)phenyl]propionic acid, were labelled with tritium. The hydroxy-metabolite containing tritium at α- and β-carbons of the propionic acid moiety was prepared by catalytic reduction of the olefinic double bond in 2-[4-(2-methyl-2-hydroxypropyl)phenyl]propenoic acid with tritium-enriched
布洛芬的两种主要代谢物 2-[4-(2-羧丙基)苯基]丙酸和 2-[4-(2-甲基-2-羟丙基)苯基]丙酸用氚标记。在丙酸部分的α-和β-碳上含有氚的羟基代谢物是通过用氚催化还原 2-[4-(2-甲基-2-羟丙基)苯基]丙烯酸中的烯烃双键制备的。富氢。氚标记在羧基代谢产物的两个羧基 α 处的两个碳原子上是通过最初交换本工作中合成的相应二丙二酸衍生物的羧基氢,然后进行脱羧来实现的。在此过程中,每种丙二酸组分的羧基之一会以二氧化碳的形式丢失,从而将其氚/氢原子转移到 α-碳上。
