A metal-free synthesis of arylamines via the direct amination of phenols using easily accessible aminating reagents provides a versatile route to a broad range of arylamines with various functionalities in good yield. By using a two-step route of amination and oxidative coupling reaction, three naturally occurring carbazole alkaloids are synthesized from commercially available phenols: murrayafoline A, mukonine, and clausenine.
