Pyrazoles, isoxazoles (seebelow Major classes of heterocyclic compounds: Five- and six-membered ringswith two or more heteroatoms), and many less-common heterocycles can besynthesized by this method.
Heterocyclic compounds are of very much interest in our daily life. Heterocyclic compounds have one or more hetero atoms in their structure. They may be cyclic or non cyclic in nature. Heterocyclic compunds have a wide range of application. They are predominantly used as pharmaceuticals, as agrochemicals and as veterinary products. They also find applications as sanitizers, developers, antioxidants, as corrosion inhibitors, as copolymers, dye stuff. They are used as vehicles in the synthesis of other organic compunds. Some of the natural products e.g. antibiotics such as penicillin’s, cephalosporin; alkaloids such as vinblastine, morphine, reserpine etc. have heterocyclic moiety.

This fact can be applied to heterocycle synthesis in that it is frequentlypossible to make such intermediate compounds by other routes; theseintermediates then cyclize readily to form the desired ring.
In general, synthetic methods and physical and chemical propertiesof the saturated and the partly unsaturated heterocyclic compounds closelyresemble those for their acyclic (noncyclic, or open-chain) analogs.

Chlorophyll and heme, which are derivatives pf porphyrin ring system are the components required for the photosynthesis and for oxygen transport in higher plants and in animal. Essential diet ingredients such as thiamin (vitamin B1), riboflavin (vitamin B2), pyridoxol (vitamin B6), nicotinamide (vitamin B3) and ascorbic acid (vitamin C) are heterocyclic compounds.
