Herein, we report a direct method for the synthesis of α-imidoketones and α-azolylketones via hypoiodite-catalyzed oxidative α-C−N coupling of ketones with the corresponding imides and azoles, respectively. The use of inorganic base additives such as cesium carbonate in the presence of 18-crown-6 as a phase transfer catalyst was crucial to induce high reactivity. Control experiments revealed that the
在此,我们报道了一种通过次
碘酸盐催化酮与相应酰亚胺和唑的氧化 α-C−N 偶联直接合成 α-
亚胺酮和 α-唑基酮的方法。在 18-crown-6 存在下使用
碳酸铯等
无机碱添加剂作为相转移催化剂对于诱导高反应性至关重要。对照实验表明,碱性添加剂不仅可能促进高周转次
碘酸盐催化,而且还参与偶联配偶体的活化。
