<i>C</i>₁‐Symmetric Monosubstituted Chiral Diene Ligands in Asymmetric Rhodium‐Catalyzed 1,4‐Addition Reactions

Abstract

One trumps two: Monosubstituted chiral bicyclo[2.2.2]octadiene ligands, derived from carvone, form complexes with rhodium to catalyze the asymmetric addition of boronic acid substrates to α,β-unsaturated ketones (see scheme). The 1,4-adducts are produced in good yield and high enantioselectivity.
