N,N‐Dimethylaminophenyl moiety is a common fragment in medicinal chemistry as several pharmaceuticals bearing this privileged motif are on the market and under clinical evaluation. Oxidative N‐demethylation is generally regarded as the major metabolic pathway. However, pharmacokinetics, metabolites studies as well as the further structural modification are precluded by the impracticality of chemical
N,N-二甲基氨基苯基部分是药物化学中的常见片段,因为带有这种特权基序的几种药物已在市场上出售并正在临床评估中。氧化性N-去甲基化通常被认为是主要的代谢途径。但是,化学合成的不切实际性排除了药代动力学,代谢产物的研究以及进一步的结构修饰。这里,我们报告,乙酸可以加速显著可见光photoredox催化Ñ的-demethylation N,N- -dimethylaminophenyl衍生物。这种方法很容易进行大规模反应,甚至可能用于潜在的工业生产。
