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
A mild and efficient synthesis of various 3-brominated azaindoles and diazaindoles was developed by regioselective halogenation of the parent systems. This practical and high-yielding transformation was achieved with copper(II) bromide in acetonitrile at room temperature.
