An efficient deuteration process of α‐C−H bonds in various carbonyl‐based pharmaceutical compounds has been developed. Catalytic reactions are initiated by the action of Lewis acidic B(C6F5)3 and D2O, converting a drug molecule into the corresponding boron‐enolate. Ensuing deuteration of the enolate by in situ‐generated D2O+−H then results in the formation of α‐deuterated bioactive carbonyl compounds
在各种基于羰基的药物化合物中,已经开发了一种高效的α -C-H键氘代过程。催化反应是通过路易斯酸性B(C 6 F 5)3和D 2 O的作用引发的,将药物分子转化为相应的硼-烯酸酯。随后通过原位生成的D 2 O + -H对烯醇化进行氘化,然后导致α氘化的生物活性羰基化合物的形成,氘的掺入率高达98%以上。
