been reported to be metabolites of the parent drugs in vivo. The products resulted mainly from aromatic hydroxylation, and are not readily accessible by conventional synthesis. Thus, the described reaction may be useful in drug discovery whenever a facile synthetic access is more important than high yields (e.g., for a fast derivatisation of compounds or the preparation of metabolites).

对几种药物(氯氮平,氯丙嗪,丙咪嗪,丁螺环酮,地尔硫卓和普萘洛尔)进行改良的Udenfriend条件(Fe 2+ / Mn 2+ / EDTA /抗坏血酸/ O 2)。从每个反应中,可以得到1至8%的氧化产物,总产率为1–8%。据报道,其中许多产品(14种中的9种)是母体药物在体内的代谢产物。产物主要由芳族羟基化产生,并且常规合成不易获得。因此,只要简便的合成途径比高产率更为重要(例如,对于化合物的快速衍生化或代谢物的制备),所描述的反应就可能在药物开发中有用。水溶性差的化合物无法转化,这是该方法的重要限制。
