Abstract
Selective addition of radicals to isonitriles enables a general route for the preparation of N-heteroaromatics. This method utilizes alkenes as synthetic equivalents of alkynes by coupling homoallylic ring expansion to yield the formal 6-endo products with aromatization via stereoelectronically assisted C-C bond scission.
