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. Computed Properties of C3H3N3O2
1,2,3-Triazole-4-carboxylic acid (14 mg, 124 mumol), DIPEA (86.3 muL, 496 mumol) and HATU (47.1 mg, 124 mumol) were combined in DMF (0.2 mL) and stirred for 5 minutes at room temperature. This was then combined with (2S,4R)-4-amino-5-biphenyl-4-yl-2-hydroxymethyl-2-methyl-pentanoic acid benzyl ester (50 mg, 120 mumol). The resulting mixture was stirred for 15 minutes and the reaction was quenched with AcOH. The product purified by preparative HPLC and lyophilized to yield the title compound (13 mg; purity 95%). MS m/z [M+H]+ calc’d for C29H30N4O4, 499.23. found 499.4.
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.
