  Diarylation of Alkenes by a Cu-Catalyzed Migratory Insertion/Cross-Coupling Cascade

  摘要：

  A strategy for the catalytic diarylation of alkenes is presented. The method involves the migratory insertion of alkenes into an Ar-Cu complex to generate a new C(sp(3))-Cu complex, which subsequently undergoes reaction with an aryl iodide to constitute a vicinal diarylation of an alkene. The method provides access to benzofuran- and indoline-containing products. Furthermore, highly diastereoselective examples are presented, allowing access to complex, stereochemically rich structures from simple alkene starting materials.

  Practical Radical Cyclizations with Arylboronic Acids and Trifluoroborates

  摘要：

  Practical radical cyclizations using organoboronic acids and trifluoroborates take place in water, open to air, and In a scalable fashion employing catalytic silver nitrate and stoichiometric potassium persulfate. Both Pschorr-type cyclizations and tandem radical cyclization/trap cascades are described, Illustrating the utility of these mild conditions for the generation of polycyclic scaffolds.

• Copper-Catalyzed Regio- and Stereoselective Intermolecular Three-Component Oxyarylation of Allenes

  A copper(II)-catalyzed intermolecular three-component oxyarylation of allenes using arylboronic acids as a carbon source and TEMPO as an oxygen source is described. The reaction proceeded under mild conditions with high regio- and stereo-selectivity and functional group tolerance. A plausible reaction mechanism is proposed, involving carbocupration of allenes, homolysis of the intervening allylcopper(II), and a radical TEMPO trap.
