New discoveries in chemical research and development 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 belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Formula: C2H3N3
j0294] To 3-bromo-6-methylpicolinonitrile (2.2 g, ii mmol) in DMF (28 mE) was added K2C03 (i .7 g, i2 mmol) and 2H-i,2,3-triazole (650 pL, ii mmol). The mixture was heated to iOO C. for 36 h, cooled to rt and extracted with EtOAc. The combined organics were dried (Na2504) and concentrated. Purification via silica gel chromatography (i 0- i 00% EtOAc in hexanes) gave the title compound (i g, 48%).
