Abstract
Seven membered heterocyclic Azepine and its derivatives have great pharmacological
and therapeutic implications. In this review, the literature of the last fifty years has
been exploited for the synthesis, reaction, and biological properties of these seven-member
heterocyclic compounds. Most of the mechanisms involved the ring expansion of either five
or six-membered compounds using various methods such as thermally, photo-chemically, and
microwave irradiation. The systematically designed schemes involve the synthesis of different
derivatives of azepine, azepinone, azepane, etc., using similar moieties by various researchers.
However, there is much work yet to be done in the biological section, as it is not
explored and reported in the literature; therefore, N-containing seven-membered heterocycles
still have much scope for the researchers.

Abstract
Many medium ring-sized heterocyclic motifs are found in naturally occurring compounds
of significant biological activity which led to the investigation of the biological activity of simpler
heterocyclic compounds accommodating these ring systems. Therefore, the development of newer
synthetic methodologies to access such ring systems has remained an important activity over the last
few decades. However, common methods of their synthesis are usually associated with thermodynamic
disadvantages. Many metal-mediated transformations e.g., Heck reaction, Suzuki reaction, etc.
tend to overcome some of these effects but at the cost of environmental disadvantages. In recent
years, several green chemical techniques have found useful applications in the synthesis of such ring
systems. In particular, the use of microwave technology has provided better opportunities. The present
review attempts to highlight many synthetic approaches developed for the synthesis of such heterocyclic
scaffolds of pharmacological interest involving condensation reaction, coupling reaction,
Multi-component reaction, Cyclo-addition reaction, Dipolar cycloaddition reaction, etc. An emphasis
has also been given on the distinct advantages offered by microwave application over classical approaches,
wherever such knowledge is available.
