hydrogen/deuteriumexchange is an important method to access deuterated compounds for chemical and biological studies. Herein is reported the first method for the regioselective α-deuteration of enals and enones. The transformation features D2O and AcOD as deuterium sources and amines as organocatalysts. The deuteration strategy is scalable and works on enals with a variety of substituted arene or heterocycle
特定地点的氢/氘交换是获取用于化学和生物研究的氘化化合物的重要方法。本文报道了第一种对 enals 和 enones 进行区域选择性 α-氘化的方法。转化的特点是 D 2 O 和 AcOD 作为氘源,胺作为有机催化剂。氘化策略是可扩展的,适用于具有各种取代芳烃或杂环基序以及烯酮的 enal。该方法已应用于氘代药物前体的合成。
