Abstract
In this short review, including 113 references, issues related to dibenzo[b,f]oxepine derivatives are presented. Dibenzo[b,f]oxepine scaffold is an important framework in medicinal chemistry, and its derivatives occur in several medicinally relevant plants. At the same time, the structure, production, and therapeutic effects of dibenzo[b,f]oxepines have not been extensively discussed thus far and are presented in this review. This manuscript addresses the following issues: extracting dibenzo[b,f]oxepines from plants and its significance in medicine, the biosynthesis of dibenzo[b,f]oxepines, the active synthetic dibenzo[b,f]oxepine derivatives, the potential of dibenzo[b,f]oxepines as microtubule inhibitors, and perspective for applications of dibenzo[b,f]oxepine derivatives. In conclusion, this review describes studies on various structural features and pharmacological actions of dibenzo[b,f]oxepine derivatives.

Abstract
The synthesis of photoswitchable azo-dibenzo[b,f]oxepine derivatives and microtubule inhibitors were described. Subsequently, we examined the reaction of methoxy derivative 3-nitrodibenzo[b,f]oxepine with different aldehydes and in the presence of BF3·OEt2 as a catalyst. Our study provided a very concise method for the construction of the azo-dibenzo[b,f]oxepine skeleton. The analysis of products was run using experimental and theoretical methods. Next, we evaluated the E/Z isomerization of azo-dibenzo[b,f]oxepine derivatives, which could be photochemically controlled using visible-wavelength light.

Abstract
In this work, we report a novel and simple one-pot synthesis of substituted dibenzo[b,f]oxepines under transition-metal-free conditions. This cascade process involves nucleophilic aromatic substitution followed by Knoevanagel condensation, as evidenced by the isolated reaction intermediates. We have also achieved the synthesis of anticancer bauhinoxepin C in 7 steps with 5.1% overall yield using this synthetic approach.

Abstract
Microtubules (composed of α- and β-tubulin heterodimers) ubiquitous cellular polymers are important components of the cytoskeleton and play diverse roles within the cell, such as maintenance of cell structure, protein trafficking or chromosomal segregation during cell division. The polymers of tubulin play a pivotal role in mitosis and are regarded as an excellent target for chemotherapeutic agents to treat cancer. This review presents a brief overview of the synthesis and mechanism of action of new compounds targeting the dynamic of microtubule - tubulin polymerization/depolymerization. It is divided into the following parts: section I concerns targeting microtubules- tubulin-binding drugs derivatives of stilbene. In section II there are presented photoswitchable inhibitors of microtubule dynamics. Section III concerns using macrocyclic compounds as tubulin inhibitors. In this review, the authors focused primarily on reports produced inthe last five years and the latest strategies in this field.

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.

Abstract
In this report, we have described a FeCl3-catalyzed process involving intramolecular annulation of o-phenoxy diarylacetylenes via hydroarylation to afford a series of biologically potent fused seven-membered (6-7-6) ring compounds under mild reaction conditions. This reaction was believed to proceed through Friedel-Crafts type sequential carbometallation followed by protonation to produce phenyldibenz[b,f]oxepines. This method was also extended to synthesize seven-membered rings that are fused with coumarins.

Abstract
In this report a short and efficient synthesis of the dibenz[b,f]oxepin framework through intramolecular SNAr and McMurry reactions is described. The diaryl ethers required for the McMurry reaction have been obtained in good yields under microwave-assisted conditions of the reaction of salicylaldehydes with fluorobenzaldehydes without catalysts. Application of an intramolecular McMurry reaction to the synthesized diarylethers using TiCl4/Zn in THF gave the target dibenzo[b,f]oxepin system in 53%-55% yields.

Abstract
The first synthesis of the polycyclic ring systems of artocarpol A and D has been accomplished. These natural products were isolated recently from the root bark of Artocarpus rigida, and artocarpol A has been shown to have potent antiinflammatory properties. The synthesis of an artocarpol D analogue was achieved on condensation of 11H-dibenzo[b,f]oxepin-10-one with senecialdehyde. The reaction of this oxepinone with citral afforded a 2H-pyran that on subsequent irradiation afforded an analogue of artocarpol A. [reaction: see text]

Abstract
Here we report that the active component of Viagra, Sildenafil and the first metabolite, N-desmethyl-sildenafil (UK-103, 320) increased the amplitude of flash-evoked electroretinogram (ERG) of dark-adapted albino rat retina. Effects of Sildenafil and N-desmethyl-sildenafil were comparable to those of the known phosphodiesterase inhibitor, Zaprinast. The photoreceptor cell response was isolated by blocking the glial K(+) ion-buffering and the on-bipolar components of the ERG with the use of BaCl(2) (500 microM) and the specific type VI metabotropic glutamate receptor agonist, DL-2-amino-4-phosphonobutyric acid (25 microM), respectively. Zaprinast, Sildenafil and N-desmethyl-sildenafil (1 microM each) increased the amplitude of photoreceptor cell response either. Besides, Sildenafil was significantly more effective than N-desmethyl-sildenafil. These findings suggest an increased sensitivity of photoreceptor cells in the presence of Sildenafil and it is metabolite.

Abstract
Several (3-aryl-2,3-dihydrobenzofuran-3-yl)alkanamines, designed as potential antidepressant agents with analgesic properties, were synthesized and pharmacologically evaluated. While two compounds (1a, 1f) displayed potent antitetrabenazine activity, concomitant antinociceptive activity in the phenylquinone writhing assay was not observed.
