and aryl methyl ketones C(sp3), which enables the direct construction of 4-hydroxybenzil derivatives. This practical method exhibits a broad substrate scope and large-scale applicability and represents a general gateway to the hydroxybenzil natural product family. Mechanistic investigations indicated that the combination of HI with DMSO realized the oxidative carbonylation of aryl methyl ketones, while
酚C(sp 2)和芳基甲基酮C(sp 3)之间存在高度对位的C-C键偶联,可直接构建4-羟基苯甲酰衍生物。这种实用的方法具有广泛的底物范围和大规模的适用性,代表了通往羟基苯甲醚天然产物家族的一般途径。机理研究表明,HI与DMSO的结合实现了芳基甲基酮的氧化羰基化,而硼酸则充当了促进这种转化的双重功能中继剂。
