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. 288-36-8
To a solution of 2-iodobenzoic acid (3.0 g, 12.1 mmol) in DMF was added 1,2,3- triazole (1.5 g, 21.7 mmol), Cs2CO3 (7.1 g, 21.7 mmol), Cul (114 mg, 0.6 mmol), and trans-N,N?dimethylcyclohexane- 1 ,2-diamine (310 mg, 2.2 mmol). After heating at 120 C for 10 mm in amicrowave reactor, the mixture was cooled to room temperature, diluted with EtOAc, and filtered through Celite. The filtrate was concentrated in vacuo and the crude residue was purified by silica gel chromatography (MeOH in DCM with 0.1% AcOH) to give Intermediate N as the faster eluting isomer. ?H NMR (DMSO-d6, 500MHz) oe 13.05 (brs, 1 H), 8.12 (s, 2H), 7.8 1-7.52 (m, 4H).
