We describe here a tandem catalytic route to prepare imidazoles in a single operation from aryl iodides, imines and CO. The reaction involves a catalytic carbonylation of aryl halides with imines to form 1,3-dipoles, which undergo spontaneous 1,3-dipolar cycloaddition. Overall, this offers an alternative to coupling reactions to construct the (hetero)aryl-imidazole motif, where variation of the building
我们在这里描述了一种串联催化路线,通过单次操作由芳基碘化物、亚胺和CO制备咪唑。该反应涉及芳基卤化物与亚胺的催化羰基化形成1,3-偶极子,然后发生自发的1,3-偶极环加成反应。总体而言,这为构建(杂)芳基-咪唑基序的偶联反应提供了一种替代方案,其中结构单元的变化可以允许合成广泛的咪唑家族,并独立控制所有取代基。
