Per-6-amino-beta-cyclodextrin (per-6-ABCD), acting simultaneously as a supramolecular ligand for CuI and host for aryl bromides, catalyzes N-arylation of imidazole with aryl bromides under mild conditions. This simple method proceeds with excellent yield for the coupling of imidazole with various substituted aryl bromides demonstrating good tolerance of other functionalities.
全-6-氨基-β-环糊精(全-6-ABCD),同时作为碘化亚铜的超分子配体和芳基溴化物的主体,在温和条件下催化咪唑与芳基溴化物的N-芳基化反应。这种简单的方法在咪唑与各种取代芳基溴化物的偶联反应中具有优异的产率,对其他官能团表现出良好的耐受性。
