Abstract
A novel [1+1+3] annulation of AgNOx, isocyanides, and isocyanates for the selective synthesis of 1,2,4-triazoles is presented herein. In this transformation, AgNOx and isocyanates are used as nitrogen sources instead of the traditional hydrazine or diazonium reagents. This process also involves N-O/C-H/C═N bond cleavage and the construction of new N-N/C-N bonds with a good substrate scope and functional group tolerance.

Abstract
Fluorinated heterocycles have attracted extensive attention not only in organic synthesis but also in pharmaceutical and medicinal sciences due to their enhanced biological activities than their non-fluorinated counterparts. Triazole is a simple five-membered heterocycle with three nitrogen atoms found in both natural and synthetic molecules that impart a broad spectrum of biological properties including but not limited to anticancer, antiproliferative, inhibitory, antiviral, antibacterial, antifungal, antiallergic, and antioxidant properties. In addition, incorporation of fluorine into triazole and its derivatives has been reported to enhance their pharmacological activity, making them promising drug candidates. This mini-review explores the current developments of backbone-fluorinated triazoles and functionalized fluorinated triazoles with established biological activities and pharmacological properties.

Abstract
A new method was developed for synthesis of 1,2,4-triazole-3-carboxylates 5a-p and 6 from nitrilimines 3a-p through amination and heterocyclization two-steps reactions. All of 1,2,4-triazole-3-carboxylates 5 and 6 were characterized by spectroscopy technique. Based on the SAR study of anti-inflammation activity, most of these compounds showed potential anti-inflammatory activity on NO inhibition in LPS-induced RAW 264.7 cells (IC50 < 7.0 µM) compared with Celecoxib and Indomethacin. Several potential compounds 5b-h, 5j, 5l, 5n, and 5o were subjected to in vitro cyclooxygenase COX-1/COX-2 inhibition assays. Compound 5d showed extraordinary COX-2 inhibition (IC50 = 17.9 nM) and the best selectivity (COX-1/COX-2 = 1080). Furthermore, 5 mg/kg compound 5d exhibited better in vivo anti-inflammation and gastric protection results compared to 10 mg/kg Indomethacin. Docking experiments of 5d into COX-2 binding pocket have been evaluated. Following the bioactivities experimental data, the potential drug candidate 5d, significantly exhibited better anti-inflammatory effect than Indomethacin.

Abstract
An efficient one-flask cascade method for synthesis of the multi-substituted 1,2,4-triazoles via chlorotrimethylsilane as a promoter was developed. Firstly, nitrilimines were transformed to hydrazonamides as intermediate in high yield by treatment with commercially available hexamethyldisilazane. Subsequently, the mixture was added with corresponding acyl chloride and heated in the presence of pyridine to give the corresponding multi-substituted 1,2,4-triazoles via chlorotrimethylsilane promoted heterocyclization reaction. The utility of method was demonstrated to synthesize CB1 ligands including Rimonabant analogue 4c and LH-21 3 for modeling study. All synthesized compounds were subjected to the cAMP functional assay of CB1/CB2 receptor. Especially, compound 4g enhanced the reversal of cAMP reduction by CP59440 than LH-21 and Rimonabant analogue in CHO-hCB1 cells. In addition, the docking results showed compound 4g fits the best position with CB1 receptor. However, the ability to penetrate brain-blood barrier of compound 4g is similar with Rimonabant in MDCK-mdr1 permeability assay, which might cause CNS side effect. This study still provides the basis for further development of a potent and specific CB1 antagonist.

Abstract
In the title compound, C13H11N3S2, the triazole and thiophene rings are coplanar [dihedral angle = 6.22 (13)°]. By contrast, the phenyl ring is perpendicular to the triazole ring [dihedral angle = 85.58 (13)°], so that the molecule has an L-shape. The thiophene S atom is syn with the ring imine N atom. In the crystal, eight-membered {⋯HNCS}2 synthons form between centrosymmetrically related molecules, leading to dimeric aggregates that are connected into a supramolecular layer parallel to (101) by π–π interactions between centrosymmetrically related triazole rings [centroid–centroid distance = 3.6091 (15) Å] and C—H⋯π interactions.
