Josi or Mandy? Asymmetric conjugate addition of diboron to acyclicenones catalyzed by copper affords chiral organoboronates that possess a boronate group at the β stereocenter with excellent chemical yields and enantioselectivities (see scheme). This method accommodates the structural variation of acyclicenones and provides access to highly functionalized chiral organoboronates in one step.
