Nucleosides have important therapeutic applications that include antiviral activities against COVID viruses. It is a common strategy to convert one or multiple of the hydroxyl (OH) units in nucleosides to the corresponding ester groups to prepare nucleoside prodrugs for better performance. Due to the presence of multiple OH units in nucleosides, current protocols for access to such ester prodrugs involve
核苷具有重要的治疗应用,包括针对新冠病毒的抗病毒活性。将核苷中的一个或多个羟基(OH)单元转化为相应的酯基以制备核苷前药以获得更好的性能是一种常见的策略。由于核苷中存在多个 OH 单元,目前获取此类酯前药的方案涉及多个步骤,因为保护基团的安装和去除。在这里,我们公开了一种催化策略,允许特定 OH 单元的区域选择性功能化,而不需要保护其他 OH 基团。我们方法中的关键步骤是N-杂环卡宾催化核苷戊糖单元的选择性酰化。我们证明,可以使用我们的策略以简洁的路线制备商业上市的 COVID-19 前药,例如 molnupiravir。
