A series of new oxazoline-substituted imidazolium salts based on [2.2]paracyclophane were synthesized and characterized. The new bidentate oxazoline-carbene precursor with planar and central chirality had significant advantage than the bicyclic 1,2,4-triazolium salt derived from [2.2]paracyclophane as a monodentate carbene ligand in Cu(I)-catalyzed asymmetric β-boration of α,β-unsaturated esters, giving the desired products in high enantioselectivities and yields.

(Chemical Equation Presented) Asymmetrie 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).
