Heterocyclic compounds are organic compounds that contain a heterocyclic structure in the molecule and are the largest number of organic compounds. In addition to carbon atoms, the atoms constituting the ring also contain at least one heteroatom. The most common heteroatoms are nitrogen atoms, sulfur atoms, and oxygen atoms.This organic compound can be divided into two categories: aliphatic heterocycles and aromatic heterocycles. Heterocyclic compounds are ubiquitous in the structure of drug molecules.
