A highly efficient iodine/TBHP-mediated one-pot deoxygenative and regioselective C2-sulfonylation of quinoline N-oxides with sodium sulfinate salts has been developed. This metal, base and phosphorus-free protocol employs readily accessible and easy to handle reagents, and can be conveniently carried out at room temperature under mild conditions, providing an alternative access to a series of C2 sulfonyl
已经开发了一种高效的碘/TBHP 介导的一锅脱氧和区域选择性 C2-磺酰化喹啉 N-氧化物与亚硫酸钠盐。这种无金属、无碱和无磷的方案采用易于获得且易于处理的试剂,并且可以在温和条件下在室温下方便地进行,提供了在温和条件下获得一系列 C2 磺酰基喹啉和其他相关杂芳基砜产品的替代途径。在很短的反应时间内达到卓越的产量。
