protocol for visible-light-mediated metal-free deuteration of aldehydes in D2O with synergistic photoredox and thiol catalysis. The protocol is highly efficient, has a broad substrate scope, and shows excellent functional group tolerance and selectivity, all of which make it suitable for generating libraries of deuterated compounds. The efficient deuteration was attributed to a photoredox-catalyzed polarity-matched
醛的甲酰基处的氢/氘交换是合成氘代醛的最直接方法,这对于标记研究和药物发现很重要。在此,我们报告了一种具有协同作用的光氧化还原和硫醇催化作用的D 2 O中的可见光介导的无金属氘化醛的温和通用方案。该协议高效,具有广泛的底物范围,并显示出出色的官能团耐受性和选择性,所有这些使其适合于生成氘代化合物的文库。有效的氘代归因于醛和硫醇之间的光氧化还原催化的极性匹配的可逆氢原子转移反应。
