We developed a mild, metal-free practical method for late-stage dehydroxyazidation of structurally complex alcohols promoted by trifunctional hypervalent azido-iodine(III) reagents ABZ. The reactions proceeded via an SN2 pathway and showed excellent chemoselectivity and stereospecificity and gave the corresponding azides in high yields. The reaction mechanism was investigated by means of experiments
我们开发了一种温和、无金属的实用方法,用于由三官能高价叠氮碘 (III) 试剂 ABZ 促进的结构复杂醇的后期脱羟基叠氮化。该反应通过S N 2 途径进行,表现出优异的化学选择性和立体特异性,并以高收率得到相应的叠氮化物。通过实验和DFT计算研究了反应机理。
