A mild and efficient method for deoxygenative C2-sulfonylation of quinoline N-Oxides in the presence of a base has been developed employing extremely inexpensive SO2F2 as an activator and sodium sulfinate as nucleophilic sulfonylation source. It is noteworthy that the reaction proceeded well under metal- and oxidant-free conditions to give a variety of 2-sulfonylquinolines in medium to good yields
                                    已经开发了一种温和有效的方法,该方法在碱存在下,使用极其便宜的SO 2 F 2作为活化剂,并使用亚
磺酸钠作为亲核磺酰化源,对
喹啉N-氧化物的C2-磺酰化进行脱氧。值得注意的是,该反应在无
金属和无氧化剂的条件下进行得很好,以中等至良好的产率得到了各种2-磺酰基
喹啉。
