Description Application Efficient and Selective Catalysts for Asymmetric Synthesis Catalyst employed in an asymmetric 1,6-addition of arylzinc reagents to dienones leading to chiral 5-substituted enones. Also used in an asymmetric 1,4-addition of organoboron reagents to cyclic and acyclic α,β-unsaturated ketones with excellent enantioselectivity. Packaging 1 g in glass bottle 250 mg in glass insert
