Direct sulfamidation of 1,4-naphthoquinones using N-methoxy sulfonamides under metal-free conditions in water was developed. Base-mediated nucleophilic addition of N-methoxy sulfonamides, followed by N–O bond cleavage allowed the formation of enesulfonamides. Further, the synthesis of pyrrolonaphthoquinones proved the practicability of the current approach.
开发了在水中无金属条件下使用N-甲氧基磺酰胺直接磺酰胺化 1,4-萘醌的方法。N-甲氧基磺酰胺的碱介导亲核加成,随后 N-O 键断裂,形成烯磺酰胺。此外,吡咯并萘醌的合成证明了该方法的实用性。
