Electric Literature 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.
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), Cs2C03(7.1 g, 21.7 mmol), Cul (114 mg, 0.6 mmol), and trans-N,K- dimethylc)rclohexane-l,2-diamine (310 mg, 2.2 mmol). After heating at 120 C for 10 min in a microwave 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 H as the faster eluting isomer. 1H NMR (DMSO-d6 , 500MHz) delta 13.05 (brs, 1 H), 8.12 (s, 2H), 7.81-7.52 (m, 4H).
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.
