Reference of 288-36-8, New Advances in Chemical Research in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 288-36-8, name is 1H-1,2,3-Triazole, molecular formula is C2H3N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
A solution of 2-bromo-3-thiophene carboxylic acid (1.50 g, 7.24 mmol), 1H-1,2,3- triazole (0.600 g, 8.69 mmol), potassium carbonate (2.00 g, 14.5 mmol), and copper iodide (0.138 g, 0.724 mmol) in DMF (36.2 mL) was purged subsurface with nitrogen and heated to 75 C for 96 h. The reaction was diluted with water, washed with ether, and acidified with cone. HC1. The acidic aqueous solution was extracted 3x with EtOAc and the combined organic fractions were washed with brine, dried over magnesium sulfate, filtered, and concentrated. The crude material was purified by silica gel gradient chromatography [0-70% (1% acetic acid in EtOAc) in hexanes], to provide Intermediate C as a solid. LRMS m/z (M+H) 196.2 found, 196.1 required.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 1H-1,2,3-Triazole, hurry up and to see.
