Take five: A new method employing aryl halide carbonylation to directly access heterocycles has been described (see scheme). In a single palladium‐catalyzed reaction the catalyst mediates two consecutive carbonylation steps, thereby converting five components (aryl iodide, two units imine, and two units CO) into an imidazoline ring.
选五:描述了一种使用芳基卤化物羰基化直接访问杂环的新方法(请参见方案)。在单个钯催化的反应中,催化剂介导两个连续的羰基化步骤,从而将五种组分(芳基碘化物,两个单元亚胺和两个单元CO)转化为咪唑啉环。
