Reaction of substituted N-aryl hydroxylamines with methanesulfonyl chloride, p-toluenesulfonyl chloride, or trifluoromethanesulfonic anhydride under basic conditions leads to the rearranged 2-aminophenols (45-94%). The overall reaction sequence can be performed using polymer-supported sulfonyl chloride resin allowing for the effective conversion of N-aryl hydroxylamines to the 2-aminophenols without the need for chromatography.
在碱性条件下,取代的 N-芳基
羟胺与甲
磺酰氯、
对甲苯磺酰氯或
三氟甲磺酸酐反应,可生成重排的
2-氨基苯酚(45-94%)。整个反应过程可以使用聚合物支撑的
磺酰氯树脂进行,这样就可以有效地将 N-芳基
羟胺转化为
2-氨基苯酚,而无需使用色谱法。
