Catalytic Asymmetric Boration of Acyclic α,β‐Unsaturated Esters and Nitriles

Asymmetric β-boration of acyclic α,β-unsaturated carbonyl compounds provides ready access to enantioenriched functionalized organoboron compounds. A range of acyclic unsaturated esters and nitriles reacted with high enantioselectivity and good yields at room temperature using a copper catalyst and planar chiral diphosphine ligands (L).
