摘要
Fluorine-substituted [2.2]paracyclophane-based carbene precursors have been successfully synthesized and applied to copper-catalyzed asymmetric beta-boration of alpha,beta-unsaturated ketones. Fluorination of the planar chiral carbenes has a beneficial impact on the catalytic performance of the relevant complexes. A variety of chiral beta-boryl ketones were obtained in excellent yields (up to 99%) and with high enantioselectivities (up to 99% ee). (C) 2016 Elsevier Ltd. All rights reserved.
