Copper in Efficient Synthesis of Aromatic Heterocycles with Single Heteroatom

Aromatic heterocycles are important structural units in various naturally occurring compounds. Its abundance has drawn attention of synthetic chemists for decades. In the current scenario, new methodologies employing cheap transition metal reagents are highly desirable for efficient and practical synthesis of heterocyclic compounds. In this review article, strategies to synthesize aromatic heterocycles by inexpensive copper reagents have been discussed.
