A Doyle–Kirmse reaction of N-sulfonyl-1,2,3-triazole with 3,3-difluoroallyl sulfide through a Rh(II)-catalyzed [2,3]-sigmatropic rearrangement has been developed, which provides an efficient access to multifunctional quaternary centers containing aryl, imino, thio, and brominated gem-difluoroallyl groups. The reaction features broad substrate scope with moderate to excellent yields. The applicability
已经开发了N-磺酰基-1,2,3-三唑与 3,3-二氟烯丙基硫醚通过 Rh( II ) 催化的 [2,3]-σ 重排的 Doyle-Kirmse 反应,它提供了一种有效的途径含有芳基、亚氨基、硫基和溴化偕二氟烯丙基的多功能季中心。该反应具有广泛的底物范围和中等至优异的产率。该方法的适用性通过克级合成和进一步转化得到证实。
