摘要:The present invention relates to methods for the synthesis of indoles. In particular, the invention relates to the coupling of an a-haloenone or a-haloenal with an ortho-halonitroarene to form an ortho-(enone)nitroarene or ortho-(enal)nitroarene. Reductive cyclization of an ortho-(enone)nitroarene or ortho-(enal)nitroarene affords access to indole compounds.
