摘要

The indole nucleus is found in numerous biologically important natural products and synthetic drugs. Indoles with carbon substituents in the 3-position are of pivotal importance in central-nervous-system (CNS) drugs, particularly for antipsychotics.[1] Although many indole syntheses are known, a truly general approach has yet to be discovered.[2, 3] Herein we report a route to 3-substituted indoles from ortho-dihalobenzenes and allylic amines ...
