a visible-light-induced iridium-promoted direct bifunctionalization of 3-butenoic acid with bromodifluoromethyl heteroarylsulfones. This methodology enables the concurrent introduction of difluoromethyl heteroarylsulfone and bromine groups into 3-butenoic acid under mild reaction conditions. Various α-substituted 3-butenoic acids and bromodifluoromethyl heteroarylsulfones were found to be compatible
在此,我们报道了可见光诱导的铱促进的 3-丁烯酸与溴二氟甲基杂芳基砜的直接双官能化。该方法能够在温和的反应条件下将二氟甲基杂芳基砜和溴基团同时引入3-丁烯酸中。各种α-取代的3-丁烯酸和溴二氟甲基杂芳基砜被发现是相容的,以中等至良好的收率产生相应的产物。该方法为氟代羧酸衍生物的合成开辟了一条新路线。
