Environmentally Friendly Approach

The design of the environmentally friendly approach to the synthesis of biologically important compounds without compromising the yield has been the focus of many chemists in recent years. The development of the one-pot synthesis of heterocycles in the presence of Ionic Liquids (ILs), used as both environmental media and catalysts, is efficient and environmentally sustainable. This review highlights the one-pot synthesis of imidazoles in acidic ILs in the past decade. Some reviews have been conducted on imidazoles, such as their pharmacological importance. Hence, we decided to focus on their synthesis in acidic ionic liquids, which the authors are not aware of any published literature.

Heterocyclic Moiety

One-pot syntheses are a simple, efficient and easy methodology, which are widely used for the synthesis of organic compounds. Imidazoline is a valuable heterocyclic moiety used as a synthetic intermediate, chiral auxiliary, chiral catalyst and a ligand for asymmetric catalysis. Imidazole is a fundamental unit of biomolecules that can be easily prepared from imidazolines. The one-pot method is an impressive approach to synthesize organic compounds as it minimizes the reaction time, separation procedures, and ecological impact. Many significant one-pot methods such as N-bromosuccinimide mediated reaction, ring-opening of tetrahydrofuran, triflic anhydrate mediated reaction, etc. were reported for imidazoline synthesis. This review describes an overview of the one-pot synthesis of imidazolines and covers literature up to 2020.
