Nickel‐Catalyzed Regio‐ and Stereoselective Reductive Alkylative Cyclization of 1,6‐Enynes with Alkyl Bromides

Abstract A nickel‐catalyzed reductive alkylative cyclization of 1,6‐enynes with alkyl bromides has been developed. This transformation avoids the use of stoichiometric organometallic reagents and introduces alkyl groups regio‐ and stereoselectively into the products. This method provides a platform for the synthesis of carbo‐ and heterocycles that are widely found in many natural products and biologically active molecules.
