Heterocyclic sulfones, sulfonamides, and sulfonyl fluorides constitute an important structural motif in medicinal chemistry. Methods to make six-membered heteroaromatic sulfonyl compounds, however, remain challenging, and most efforts rely on commercial sulfonyl chlorides. We report herein the reaction of sodium tert-butyldimethyl silyloxymethylsulfinate with quinoline N-oxides to selectively furnish
杂环砜、磺酰胺和磺酰氟构成了药物化学中的重要结构基序。然而,制造六元杂芳基磺酰基化合物的方法仍然具有挑战性,而且大多数努力都依赖于商业磺酰氯。我们在此报告了叔丁基二甲基甲硅烷基氧基甲基亚磺酸钠与喹啉N-氧化物的反应,以选择性地提供 C2-取代的砜。甲硅烷氧基甲基亚磺酸盐可以脱保护,然后形成磺酰氟、磺酰胺和砜。这种转变是可扩展的,并且对广泛的喹啉和异喹啉功能具有广泛的适用性。
