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. 25537-64-8, name is 4,5-Dibromo-1-methyl-1,2,3-triazole, molecular formula is C3H3Br2N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
The 2.0g (8.30mmol) 1- methyl-4,5-dibromo -1H-1,2,3- triazole was dissolved in 15ml of tetrahydrofuran, cooled to -10 deg.] C, was added dropwise 4.77ml (9.55mmol) 2.0 M isopropylmagnesium chloride / tetrahydrofuran solution (commercially available, concentration 2.0M), 15ml of hydrochloric acid, using 20ml methyl tertiary butyl ether, and the extract was dried over anhydrous magnesium sulfate and concentrated under reduced pressure to 5ml, it was cooled to 0-5 crystallization, filtration, 40 dried in vacuo to give 4-bromo-1-methyl -1H-1,2,3- triazole 1.55 g, yield 90%
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 4,5-Dibromo-1-methyl-1,2,3-triazole.
