Herein, we report a user friendly, scalable and safe procedure to convert aminoheterocycles to their hydroxylated analogues with a pyrylium tetrafluoroborate salt in combination with a hydroxamic acid. The protocol is characterized by a broad functional group tolerance, permitting the selective modification of biorelevant molecules. Mechanistic experiments allowed the identification of key intermediates
在此,我们报告了一种用户友好、可扩展且安全的程序,使用四氟硼酸吡啶盐和异羟肟酸将氨基杂环化合物转化为其羟基化类似物。该协议的特点是具有广泛的官能团耐受性,允许对生物相关分子进行选择性修饰。机械实验允许识别整个转化过程中涉及的关键中间体。
