An efficient deuteration process of -C-H bonds in various carbonyl-based pharmaceutical compounds has been developed. Catalytic reactions are initiated by the action of Lewis acidic B(CF) and DO, converting a drug molecule into the corresponding boron-enolate. Ensuing deuteration of the enolate by in situ-generated DO-H then results in the formation of -deuterated bioactive carbonyl compounds with up to >98% deuterium incorporation.
已开发出一种在各种基于羰基的药物化合物中高效氘代-C-H键的方法。催化反应由路易斯酸性B(CF)和DO引发,将药物分子转化为相应的硼烯醇盐。随后原位生成的DO-H对烯醇盐进行氘代,从而形成氘掺入率高达>98%的氘代生物活性羰基化合物。
