Herein, a tunable iodization/deuterolysis protocol for phosphonium ylides by employing D2O as the deuterium source was designed. Notably, this process could be manipulated by tuning the base, thus leading to two valuable deuterated building blocks – benzyl iodides and aromatic aldehydes with broad substrate scope, good functional group compatibility and excellent deuteration degree. Concise syntheses
在此,设计了一种采用 D 2 O 作为氘源的鏻叶立德的可调谐碘化/氘解方案。值得注意的是,这个过程可以通过调整碱基来控制,从而产生两个有价值的氘代结构单元——苄基碘和芳香醛,它们具有广泛的底物范围、良好的官能团相容性和优异的氘化度。基于开发的氘代反应平台,实现了一系列氘代药物类似物的简明合成。
