A metal-free α-C–H functionalization of cyclic 1,2-diketones with aryl sulfoxides has been developed. This regioselective arylation involves nucleophilic substitution at the activated sulfoxide with a diosphenol, followed by [3,3]-sigmatropic rearrangement. This protocol can also be applied to the synthesis of polysubstituted cyclic 1,2-diketones with predictable structures by iterative arylations
已经开发了使用芳基亚砜的环状1,2-二酮的无金属α-CH官能化。这种区域选择性芳基化涉及在活化的亚砜上用二酚进行亲核取代,然后进行[3,3]-σ重排。该方案还可用于通过迭代芳基化反应合成具有可预测结构的多取代环状1,2-二酮。
