NHC‐Cu‐Catalyzed Enantioselective Hydroboration of Acyclic and Exocyclic 1,1‐Disubstituted Aryl Alkenes

Abstract

Harte Nuss zu knacken: Chirale zweizähnige NHC-Kupfer-Komplexe wurden entwickelt, die enantioselektive Hydroborierungen einer der problematischsten Substratklassen vermitteln: Acyclische und exocyclische 1,1-disubstituierte Alkene wurden mit >98 % Positionsselektivität in bis zu >98 % Ausbeute und e.r.=96.5:3.5 umgesetzt (siehe Schema, B2(pin)2=Bis(pinakolato)dibor, NHC=N-heterocyclisches Carben).
