Enantioselective Synthesis of Boron-Substituted Quaternary Carbons by NHC–Cu-Catalyzed Boronate Conjugate Additions to Unsaturated Carboxylic Esters, Ketones or Thioesters

An efficient Cu-catalyzed method for enantioselective boronate conjugate additions to trisubstituted alkenes of acyclic α,β-unsaturated carboxylic esters, ketones and thioesters is disclosed. All transformations are promoted by 5 mol % of a chiral monodentate NHC–Cu complex, derived from a readily a...
