Herein, we report on a new UFC reaction that involves the palladium-catalyzed elimination of an isocyanate fragment from an amide, with the formation of carbon–carbon and carbon–heteroatom bonds. An organometallic intermediate that is relevant to the catalytic reaction was characterized by X-ray crystallography. This UFC reaction enables the late-stage transformation of an amide functionality, allowing amides
过渡金属催化的单分子片段偶联 (UFC) 定义为通过分子(如 CO 和 CO 2)的挤出以及随后剩余片段的重组形成新化学键的过程。在此,我们报道了一种新的 UFC 反应,该反应涉及钯催化从酰胺中消除异氰酸酯片段,形成碳-碳和碳-杂原子键。通过 X 射线晶体学表征了与催化反应相关的有机金属中间体。这种 UFC 反应能够实现酰胺官能团的后期转化,从而使酰胺能够用作可转换的导向或保护基团。

Page 11037. The required annotation for compound 6j in Table 4 was inadvertently missing in our original manuscript. Footnote c has been added to 6j to note that a higher reaction temperature and a longer reaction time were required for this specific substrate, as given below. This information is also included in the revised Supporting Information. The Supporting Information is available free of charge
