即使在存在能稳定Cu(I)的三(三唑)配体的情况下,在铜催化的叠氮 - 炔烃环加成(CuAAC)反应条件下,蛋白质(牛血清白蛋白)仍会被空气氧化。厌氧条件不仅避免了蛋白质的氧化,而且使用水溶性双(三唑)Cu(I)配体极大地加速了CuAAC反应。
Oxidation of protein (bovine albumin serum) by air still occurred under the copper-catalyzed azide–alkyne cycloaddition (CuAAC) reaction conditions even in the presence of a Cu(I)-stabilizing tris(triazole) ligand. Anaerobic conditions not only avoided the oxidation of the protein, but also greatly accelerated the CuAAC reaction using a water-soluble bis(triazole) Cu(I) ligand.
