A broad‐spectrum, catalytic method has been developed for the synthesis of sulfonamides and sulfamates. With the activation by the combination of a catalytic amount of 1‐hydroxybenzotriazole (HOBt) and silicon additives, amidations of sulfonyl fluorides and fluorosulfates proceeded smoothly and excellent yields were generally obtained (87–99 %). Noticeably, this protocol is particularly efficient for
已经开发了一种广谱催化方法,用于合成磺酰胺和氨基磺酸盐。通过催化量的1-羟基苯并三唑(HOBt)和硅添加剂的结合活化,磺酰氟和氟代硫酸盐的酰胺化反应顺利进行,通常获得优异的收率(87–99%)。值得注意的是,该协议对于空间受阻的底物特别有效。催化剂的负载量通常很低,而金刚烷衍生物的十克级合成仅需要0.02 mol%的催化剂。此外,通过关键中间体磺酰氟13合成市售药物Fedratinib,已证明了该方法在药物化学中的潜力。。由于大量的胺是可商购的,因此该途径提供了进入Fedratinib类似物进行生物学筛选的简便途径。
