Chiral Aminoborane as a Chiral Proton Source for Asymmetric Protonation of Lithium Enolates Derived from 2-Arylcyloalkanones.

-The first example of asymmetric protonation using a metal-containing chiral proton source is reported. The reaction gives moderate to high asymmetric induction if the enolate possesses an aryl group at the C-2 position. Substrates like (IXb) bearing no aromatic groups give unsatisfactory results. -(YANAG-
