We report halogenated pentanidiums as phase‐transfer catalysts for the asymmetric alkylation of sulfenate anions to various sulfoxides with high enantioselectivities (up to 99 % ee) and yields (up to 99 %). This approach gives access to enantioenriched heterocyclic sulfoxides that might not be compatible with strong oxidants or organometallic reagents. Computational studies have revealed that the multiple

戊二烯作为相转移催化剂,用于将
亚硫酸根阴离子不对称烷基化为具有高对映选择性(高达99%ee)和产率(高达99%)的各种亚砜。这种方法可以获取可能与强氧化剂或有机
金属试剂不兼容的对映体富集的杂环亚砜。计算研究表明,涉及多个非共价相互作用,例如卤素键和非经典氢键。
