以重氮化合物和烯丙基硫醚/炔丙基硫醚为反应底物,通过手性辅基和大位阻配体的不对称双诱导策略,高对映选择性地实现了经由铜卡宾产生硫叶立德的不对称[2,3]-σ重排反应(Doyle-Kirmse反应).脱除手性辅基后反应最高可以得到96%ee对映选择性.机理探究实验表明,反应很可能经历了自由的叶立德重排过程.该反应被进一步应用到含手性中心烯丙基硫醚的动力学拆分中.

A highly stereoselective[2,3]-σ rearrangement of sulfur ylide derived from Cu(I) carbene and allyl/propargyl sulfides (Doyle-Kirmse reaction) is reported. High stereocontrol is achieved by a dual asymmetric induction approach which involves a chiral auxiliary on diazo substrate, and steric bulky ligand of the Cu(I) catalyst. From mechanistic study, we suggest the[2,3]-σ rearrangement process occurs through free sulfur ylide intermediate. The reaction was further applied in kinetic resolution of allyl sulfide with a chiral center.
