Heterocyclic chemistry is one of the prominent areas of organic chemistry
that synthesizes a variety of medicinally important drug moieties. Heterocycles make
up the majority of pharmaceutical medicines that imitate biologically active natural
compounds. Ionic liquids (ILs) have recently drawn more attention in relation to green
organic synthesis. Ionic liquids have evolved since their first introduction as alternative
green reaction media due to their distinct chemical and physical characteristics of nonvolatility, non-flammability, thermal stability, and regulated miscibility. Nowadays, the
scientific community has focused on using ILs as effective catalysts in different
organic transformations for synthesizing biologically active heterocycles. The current
work highlights the essential insights into the indisputable uses of ionic liquids as
effective catalysts in different organic transformations.
