A rhodium-catalyzed denitrogenative carbonylation of 1,2,3-thiadiazole with alkynes to construct (benzo)thiochromenones is developed. Both terminal and internal alkynes were compatible in this [3+2+1] cycloaddition, affording a broad range of poly-substituted thiochromenones. Unsymmetrical alkyne substrates exhibited good regioselectivity. It is noteworthy that the present strategy could be used to
开发了铑催化的 1,2,3-噻二唑与炔烃的脱氮羰基化反应以构建 (benzo)thiochromenones。末端和内部炔烃在这种 [3+2+1] 环加成反应中是相容的,提供了广泛的多取代硫代苯并噻吩酮。不对称炔底物表现出良好的区域选择性。值得注意的是,目前的策略可用于构建单环和苯并硫代苯并噻吩酮,它是 CO 插入的脱氮环化的新例子。
