derivatives via intramolecularoxidative coupling of thiosemicarbazide, using the in situ generated hypervalent iodine(III) reagents is developed. The protocol can be carried out smoothly and provides a variety of thiadiazole derivatives in moderate to excellent yields.Graphical AbstractA highly efficient method for the synthesis of thiadiazole derivatives via PhI-catalyzed intramolecularoxidative coupling

Photoredoxcatalysis with the use of a stable, reusable silica‐bound chromophore was applied to the intramolecularcyclization of a series of 2‐benzylidenehydrazinecarbothioamides to give 5‐phenyl‐1,3,4‐thiadiazol‐2‐amines. The catalyst was readily prepared by carbodiimide‐mediated coupling of commercially available amine‐functionalized silica beads to a carboxylic acid functionalized ruthenium complex

potent analogue in the series with fifteen folds more active than standard acarbose. Structureactivity relationship (SAR) studies suggested that α-glucosidase activities of triazinoindole bearing thiadiazole are primarily dependent upon on number and position of different substitutions present on phenyl parts. Molecular docking study were conducted of the optimized compounds (i.e., compound 4, 6, and
A simple, efficient and environment-friendly approach is described for the synthesis of N-alkyl-3,6-diaryl[1,2,4]triazolo[4,3-b][1,2,4]triazin-7-amines based on three-component reaction between 5-aryl-4H-1,2,4triazole-3,4-diamine, isocyanide and aldeyhde under solvent-free condition. The products are obtained in moderate to good yields and are in a state of high purity.

MS spectra. The antibacterial and antifungalactivities were evaluated by diffusion method and the anticancer activities were evaluated by MTT assay. RESULTS Twenty-seven derivatives have been synthesized in moderate to good yields. A number of derivatives exhibited potential antibacterial, antifungal and anticancer activities. CONCLUSION Compounds (1b, 1e and 1g) showed antibacterialactivity against
