been the poor relation of its oxygen counterpart. We demonstrate that on-water catalysis facilitates the rearrangement of reverse N-prenylated naphthylamines and anilines, and transforms the aromatic aza-Claisen rearrangement into a synthetically viable reaction. We use this reaction to probe the mechanism of on-water catalysis, and provide compelling support for the acid-catalysis hypothesis.
长期以来,芳族氮杂-克莱森重排一直是其氧对应物的不良关系。我们在以下方面证明了这一点:水催化作用促进了反向N-戊烯化萘胺和苯胺的重排,并将芳族氮杂-克莱森重排转化为合成上可行的反应。我们用这个反应来探究水 催化,并为酸催化假说提供有说服力的支持。
