A simple, sustainable, efficient, mild, and low‐cost protocol was developed for d‐glucose‐assisted Cu‐catalyzed Ullmann reactions in water for amides, carbamates, and nitrogen‐containing heterocycles. The reaction was compatible with diverse aryl/heteroaryl iodides, giving highly substituted pyridine, indole, or indazole rings. This method offers an attractive alternative to existing protocols, because

The copper-catalyzed N-arylation of benzamides or nitrogenheterocycles was carried out with catalytic CuI (10 mol%) in the presence of ethylenediamine (10 mol%) as a ligand and K 3 PO 4 or Cs 2 CO 3 as a base under mild conditions.
在乙二胺(10 mol%)作为配体和K 3 PO 4 或Cs 2 CO 3 作为碱存在下,用催化CuI(10 mol%)进行铜催化的苯甲酰胺或氮杂环的N-芳基化条件温和。

An array of heterocyclic amides was synthesized efficiently by combining corresponding amines and benzoyl chloride in one-pot under microwave irradiation. The reaction times were shorter, yields were higher. What is more, the regioselectivity was excellent, which made the protocol support us an entry to selective protection of diverse amino groups.
