One-Pot Synthesis of Benzoxazoles: A Promising Approach to Aromatic Heterocyclic Compounds Preparation.

Considering the necessity for broad synthetic operations, integrating various reactions into a single pot operation is an intriguing approach to improve synthetic efficiency. One-pot operations may serve as an effective way to minimize the amount of chemical waste generated, save time, avoid multiple purification processes, accomplish numerous transformations, and make multiple bonds in one pot. Therefore, "pot economy" should be considered while designing a synthesis process, since a one-pot reaction can be effective and environmentally safe. Outstanding synthesis has rapidly increased over the last ten years. This study's main goal was to illustrate various one-pot methods that lead to advantageous synthesis.
