Heterocyclic Compounds topics include: Five membered rings, structure and source of pyridine compounds, electrophilic and nucleophilc substitution in pyridine.
A heterocyclic compound is a cyclic compound that contains atoms from at least two different elements in its ring. The word "hetero" means not identical, indicating that the cyclic compound's structure has molecules that are not the same.
The ring structure of a heterocyclic compound contains carbon and other elements, such as oxygen, nitrogen, and sulfur. The simplest five-membered heterocyclic compounds are pyrrole, furan, and thiophene.
Examples of heterocyclic compounds include: All nucleic acids Most drugs Most biomass Many natural and synthetic dyes
Nitrogen heterocycles are the most common backbone in complex structures.
Examples of heterocyclic drugs include: Beta-lactam antibiotics, such as penicillins, cephalosporins, monobactams, and carbapenems Lisinopril, which is used to treat hypertension and heart failure
