New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. name: 1H-[1,2,3]Triazole-4-carboxylic acid
lH-l,2,3-triazole-5-carboxylic acid (3.1 mg, 27 muiotaetaomicron) was combined with HATU (10.4 mg, 27 muiotaetaomicron) in DMF (0.5 mL), and stirred for 10 minutes. DIPEA (4.8 mu, 27 Mmol) was added and the resulting mixture was stirred for 1 minute. Compound 2 (12 mg 27 muiotaetaomicron) dissolved in DMF (1 mL) was combined with added DIPEA (14.4 mu, 82 muiotaetaomicron) followed by addition of the activated acid solution. The resulting mixture was stirred for 30 minutes then purified by reverse phase chromatography (0-100% EtOAc/hexanes to yield Compound 3 (10
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1H-[1,2,3]Triazole-4-carboxylic acid help many people in the next few years.
