Rhodium‐Catalyzed Asymmetric Conjugate Addition of Arylboroxines to Borylalkenes: Asymmetric Synthesis of β‐Arylalkylboranes

Abstract

Asymmetric conjugate addition of arylboroxines to borylalkenes proceed in the presence of a chiral bisphosphine/rhodium complex as a catalyst to give chiral β-arylalkylboranes with high enantioselectivities (see scheme). [O]=H2O2/NaOH.
