Atropo-enantioselective biaryl coupling through C−H bond functionalization is an emerging technology allowing direct construction of axially chiral molecules. This approach is largely limited to electrophilic coupling partners. We report a highly atropo-enantioselective C−H arylation of tetralone derivatives paired with aryl boronic esters as nucleophilic components. The transformation is catalyzed
通过 C−H 键功能化进行的对映选择性联芳基偶合是一项新兴技术,允许直接构建轴向手性分子。这种方法很大程度上限于亲电偶联伙伴。我们报道了四氢萘酮衍生物与作为亲核组分的芳基硼酸酯配对的高度对映选择性 C−H 芳基化。该转化由手性环戊二烯基 (Cp x ) 铱 (III) 配合物催化,并通过高价环金属化铱物质的氧化增强还原消除来实现。
