8-Sep-21 News Now Is The Time For You To Know The Truth About 7170-01-6

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 3-Methyl-1H-1,2,4-triazole is helpful to your research.

Application of 7170-01-6, New Advances in Chemical Research in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 7170-01-6, name is 3-Methyl-1H-1,2,4-triazole, molecular formula is C3H5N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.

Prepared according to Mastalerz et al. J. Med. Chem. 1988, 31, 1190. To a solution of compounds A/B, step 1 (1.60 g, 3.44 mmol) in ACN:water (2:1, 45 mL) was added K2S2O8 (1.86 g, 6.88 mmol) followed by K2HPO4 (1.50 g, 8.60 mmol). The resulting mixture was heated to 90 C. for 4 h, whereupon it was cooled to rt then diluted with EtOAc and the layers separated. The aqueous layer was extracted with EtOAc (3 x) and the combined organic layers were dried over Na2SO4 and concentrated in vacuo. The crude residue was purified via silica gel chromatography (MeOH-DCM, 10%), to afford the title compounds (mixture, 670 mg, 62%) as a white solid. The mixture was further purified via chiral HPLC (Chiralcel-OJ, 2×25 cm, EtOH-Hexanes, 18%), affording compound A (250 mg) and compound B (240 mg).

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 3-Methyl-1H-1,2,4-triazole is helpful to your research.
