Abstract

Indoles (1) are an important class of N-heterocycles present in many natural products and pharmaceuticals.[1] Their synthesis presents a great challenge, and a range of new synthetic approaches to indoles have been reported in recent years.[2] Metal-catalyzed or- mediated methods have proved to be especially useful.[3] The classical Fischer indole synthesis [4] starting from aryl hydrazines [5, 6] 2 and ketones 3 is still extensively used, ...
