A chemoselective functional group installation through catalytic hydroxy group selective conjugate addition of amino alcohols to a variety of functionalized α,β-unsaturated sulfonyl derivatives was developed. Azide group installation for click chemistry and facile fluorescent labeling onto the less reactive hydroxy group demonstrated the synthetic utility of the present chemoselective catalysis. Moreover
通过将氨基醇催化羟基选择性共轭加成到各种官能化的α,β-不饱和磺酰基衍生物上,开发了化学选择性官能团。用于点击化学的叠氮基装置和在反应性较低的羟基上的简便荧光标记证明了本化学选择性催化的合成效用。此外,首次实现了未保护的氨基二醇的化学和区域选择性反应。
