organophotoredox-catalyzed stereoselective allylic arylation of MBH acetates with a palette of diaryliodonium triflates (DAIRs) to provide the corresponding trisubstituted alkenes in moderate to good yields. The method could be extended to three-component coupling involving 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) adduct (DABSO) as a sulfur dioxide surrogate for the synthesis of biologically relevant
我们报道了一种有机光氧化还原催化的 MBH 乙酸酯与二芳基碘鎓三氟甲磺酸盐 (DAIR) 的立体选择性烯丙基芳基化反应,以中等至良好的产率提供相应的三取代烯烃。该方法可以扩展到三组分偶联,涉及 1,4-二氮杂双环[2.2.2]辛烷双(二氧化硫)加合物(DABSO)作为二氧化硫替代物,用于合成生物学相关的烯丙基砜。这两个反应都是在温和的条件下进行的,具有广泛的范围、稳健性和明显的官能团耐受性。
