trifluoromethoxylation with only two successful reports since the first discovery. Here, by subtly tuning the leaving group, protecting group, ligand structure, reaction temperature, solvent and base, we finally realized a copper-catalyzed enantioselective trifluoromethoxylation of propargyl sulfonates for the first time.
目前,直接不对称三
氟甲氧基化反应仍然面临巨大挑战,自首次发现以来仅有两篇成功报道。在这里,通过巧妙地调整离去基团、保护基团、
配体结构、反应温度、溶剂和碱,我们终于首次实现了
