Kinetic Resolution of BINOLs and Biphenols by Atroposelective, Cu-H-Catalyzed Si-O Coupling with Hydrosilanes.

ABSTRACT: A nonenzymatic kinetic resolution of monoprotected BINOL and biphenol derivatives by atroposelective Si-O coupling with hydrosilanes is described. The reaction relies on a previously unprecedented Cu-H-catalyzed silylation of phenols. The catalyst system consisting of CuCl, (R,R)-Ph-BPE, and NaOtBu enables the enantioselective coupling of the phenolic hydroxy group with a hydrosilane with moderate to good selectivity factors.
