Azepanes or azepines are structural motifs of many drugs, drug candidates and evaluated lead compounds. Even though compounds having N-heterocyclic 7-membered rings often found in nature (e.g. alkaloids), the natural this group rather rare as approved therapeutics. Thus, recently studied azepane azepine-congeners predominantly consist semi-synthetically synthetically-obtained scaffolds. In review a comparison drugs investigated leads was proposed taking into regard their aspects (stereochemistry), biological activities, pharmacokinetic properties confirmed molecular targets. The N-heterocycles reveal wide range not only against CNS diseases, but also e.g. antibacterial, anticancer, antiviral, antiparasitic allergy agents. As most potential structures, belonging to N-heterocycles, synthetic scaffolds, report reveals different efficient metal-free cascade approaches useful synthesize both simple azepine-containing congeners those oligocyclic structures. Stereochemistry azepane/azepine fused systems, view data binding with targets, is discussed. Apart from we compare advances SAR studies (mainly 2018 2023), whereas related part concerning various domino strategies focused on last ten years.
