Formal Asymmetric Hydrobromination of Styrenes via Copper-Catalyzed 1,3-Halogen Migration.

ABSTRACT: An enantioselective Cu(I)-catalyzed 1,3-halogen migration reaction accomplishes a formal hydrobromination by transferring a bromine activating group from a sp² carbon to a benzylic carbon in good er and with concomitant borylation of the Ar-Br bond. Computational modelling aids in understanding the reaction outcome and suggests future directions to improve the formal asymmetric hydrobromination. The benzyl bromide can be displaced with a variety of nucleophiles to produce a wide array of functionalized products.
