arylhydroxylamine using vinyliodonium salts as vinylation reagents to generate a transient O-vinyl-N-arylhydroxylamine that rapidly undergoes a [3,3]-sigmatropic rearrangement and subsequent cyclization/rearomatization to form a substituted indole. A wide range of highly substituted indoles and benzoindoles can be afforded in good yields. This approach is readily scalable, and the scope and application of this process
在本文中,我们开发了一种铜-催化ö使用vinyliodonium盐作为乙烯化试剂以产生瞬时arylhydroxylamine的-vinylation ö -vinyl- Ñ -arylhydroxylamine即迅速经历[3,3] -sigmatropic重排和随后的环化/ rearomatization以形成取代的吲哚。可以以良好的产率提供各种高度取代的吲哚和苯并吲哚。此方法易于扩展,并介绍了此过程的范围和应用。
