A photoredox-mediated protocol for the synthesis of α-alkoxy-β-ketosulfoxides and α,β-dialkoxysulfoxides using alkynes, thiol, and alcohols is reported. This work presents a rare single-step synthesis of α-substituted sulfoxides, involving tandem introduction of a thiol and alcohol as a key enabling advancement. Furthermore, the method can be easily employed to access vinyl sulfoxides and β-ketosulfoxides
报道了使用炔烃,硫醇和醇类的光氧化还原介导的方案,用于合成α-烷氧基-β-酮亚砜和α,β-二烷氧基亚砜。这项工作提出了一种罕见的单步合成α-取代的亚砜的方法,涉及串联引入硫醇和醇作为实现改进的关键。此外,该方法可以容易地用于获得乙烯基亚砜和β-酮亚砜。
