Asymmetric copper-catalyzed addition of grignard reagents to aryl alkyl ketones

Madduri, Ashoka V. R.,Harutyunyan, Syuzanna R.,Minnaard, Adriaan J.

supporting information; body text, p. 3164 - 3167 (2012/05/05)

Chiral tertiary alcohols: A copper(I) catalyst with a chiral ferrocenyl diphosphine ligand facilitates the additive-free 1,2-addition of readily available Grignard reagents to aromatic ketones, thus providing access to chiral tertiary alcohols with excellent yields and enantioselectivities.
