Synthetic Route of 103755-58-4, 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. 103755-58-4, name is (1-Phenyl-1H-1,2,3-triazol-4-yl)methanol, molecular formula is C9H9N3O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
General procedure: 1-Azido-4-methylbenzenes 1 (0.3 mmol), propargyl alcohol 2 (0.36 mmol), CuI (0.03 mmol),NaAsc (0.06 mmol), and 2 mL solvent were added to a 15 mL pressure tube. The tube was thensealed, and the mixture was stirred at 80 C for 5 hours. After the reaction completed, the abovesystem was added with KMnO4 (0.75 mmol) and Na2CO3 (0.45 mmol), and stirred at 80 C for 8h until the reaction completed. Then, Ag2O (0.03 mmol) and K2S2O7 (0.6 mmol) were added tothe tube and the mixture was conducted at 100 C for 24 h until the transformation finished byTLC analysis. H2O (25 mL) was added to the mixture and the system was extracted with EtOAc (3× 20 mL). The combined organic layer was washed with brine (3 × 5 mL), dried with Na2SO4, andconcentrated under reduced pressure to afford the crude product. Purification by columnchromatography on silica gel with EtOAc-PE (1:3) afforded the desired product 3.
In the meantime we’ve collected together some recent articles in this area about (1-Phenyl-1H-1,2,3-triazol-4-yl)methanol to whet your appetite. Happy reading!
