Abstract: Amino heterocycles are important in drug design due to their unique intrinsic and
physicochemical properties. Though these molecules look simple, their selective reduction is
challenging because of their rich electron density in the ring. Additionally, reducing nitro
groups in heterocycles is crucial in designing different materials. With this in view, several
reduction methods have been developed and applied to various heterocyclic compounds.
However, there is no dedicated report on these special types of compounds. With careful
analysis, the studies are systematically summarized from conventional methods to advance
materials based on their catalytic activity, durability, recyclability, and stability. Further, detailed
insights are discussed to motivate chemists working in catalysts.
