History of Heterocyclic Chemistry: The history of heterocyclic chemistry began in the 1800s, in step with the development of organic chemistry. Some noteworthy developments
IMPORTANCE OF HETEROCYCLIC CHEMISTRY: A …
Three different group pf pharmaceutical with structures related to natural products are described briefly below as illustrations of the ways in which natural products chemistry interacts with synthetic heterocyclic chemistry.
Heterocyclic compunds have a wide range of application: they are predominant among the type of compounds used as pharmaceuticals , as agrochemicals and as veterinary products. They also find applications as sentizers, developers, antioxidants, as corrosion inhibitors, as copolymers, dyestuff 6.They are used as vehicles in the synthesis of other organic compunds.
Synthesis of Heterocycles - Chemistry
General features of Heterocyclic Compounds: The most common heterocycles are those having five- or six-membered rings and containing heteroatoms of nitrogen (N), oxygen (O), or sulfur (S). The best known of the simple heterocyclic compounds are pyridine, pyrrole, furan, and thiophene. A molecule of pyridine contains a ring of six atoms-five carbon atoms and one nitrogen atom. Pyrrole, furan, and thiophene molecules each contain five-membered rings, composed of four atoms of carbon and one atom of nitrogen, oxygen, or sulfur, respectively 1.

Another example , ocatanol 9 can be used to mimic the amphiphilic nature of lipid, because it has a polar head group ( primary alcohal) and a long hydrocarbon chain as tail, such as that oh fatty acids which make up part of a lipid membrane. Armed with this understanding, the organic chemist can ‘tailor’ a structure to meet a particular need by modifying the heterocyclic component.
Synthesis of O -Heterocycles - Organic Chemistry Portal
INTRODUCTION: Any of a major class of organic chemical compounds characterized by the fact that some or all of the atoms in their molecules are joined in rings containing at least one atom of an element other than carbon. The cyclic part of heterocyclic indicates that at least one ring structure is present in such a compound, while the prefix hetero refers to the noncarbon atoms, or heteroatoms, in the ring. In their general structure, heterocyclic compounds resemble cyclic organic compounds that incorporate only carbon atoms in the rings but the presence of the heteroatoms gives heterocyclic compounds physical and chemical properties that are often quite distinct from those of their all-carbon-ring analogs.

Heterocyclic compunds are also finding an increasing use as intermediate in organic synthesis[10-12]. Very often this is because a relatively stable ring system can be carried through a number of synthetic steps and then cleaved at the required stage in a synthesis to reveal other functional groups. For e.g. 4-chloro-5(4H)-oxazolones are useful intermediates 13 in organic synthesis. In particular hydrolytic cleavage affords α-chloro-αacylaminoketones. More ever they are the logical intermediate to prepare 4-(phospho-ranylidene)-5(4H)-oxazolones, that are very important and useful ligands.

One will also find articles related to physical organic chemistry studies on heterocyclic compounds, mechanistic studies of reactions leading to heterocyclic compounds and studies of the photophysical properties of heterocyclic compounds, just to name a few.
