1,2,3-Thiadiazoles are among the most important heterocyclic motifs with wide applications in natural products and medicinal chem. Herein, authors disclosed a tandem reaction for the synthesis of structurally diverse 1,2,3-thiadiazoles from 3,4-dichloroisothiazol-5-ketones and hydrazines. This method is characterized by free of external oxidants or sulfur requirements, mild reaction conditions, broad substrate scope and easy purification5-Bromo-2-chloropyridine(cas: 53939-30-3Quality Control of 5-Bromo-2-chloropyridine) was used in this study.
5-Bromo-2-chloropyridine(cas: 53939-30-3) belongs to pyridine. Pyridines, quinolines, and isoquinolines have found a function in almost all aspects of organic chemistry. Pyridine has found use as a solvent, base, ligand, functional group, and molecular scaffold. As structural elements, these moieties are potent electron-deficient groups, metal-directing functionalities, fluorophores, and medicinally important pharmacophores.
