title: Application of secondary alkyl halides to a domino aryl alkylation reaction for the synthesis of aromatic heterocycles.
abstract: A palladium-catalyzed, norbornene-mediated ortho-alkylation reaction of aryl iodides with secondary alkyl halides is described. Intermolecular or intramolecular ortho-alkylation proceeds in a domino process with various termination steps, generating two new carbon-carbon or carbon-nitrogen bonds in one pot, to afford an array of polycyclic heterocycles. The use of enantioenriched substrates has shown that this palladium-catalyzed reaction is stereospecific, proceeding with minimal erosion of ee.
