sulfonylation of heteroaromatic N-oxides with sodium sulfinates in water at ambient temperature under metal- and oxidant-free conditions has been developed. The mild reaction conditions, high reaction efficiency, operational simplicity, short reaction time and remarkable functional-group compatibility make the developed protocol very attractive for the preparation of 2-sulfonyl N-heteroaromatic compounds.
摘要建立了一种在环境温度下在无金属和无氧化剂条件下通过杂芳族N-氧化物与亚磺酸钠的磺酰化反应合成各种2-磺酰基喹啉/吡啶的环保方案。温和的反应条件,高的反应效率,操作简便,反应时间短和显着的官能团相容性使所开发的方案对于制备2-磺酰基N-杂芳族化合物非常有吸引力。
