摘要 |
One aspect of the present invention relates to asymmetric catalytic nitroaldol (Henry) reactions with ketones as the electrophilic component. In one embodiment, the present invention relates to asymmetric nitroaldol reactions with alpha-keto esters catalyzed by a new C6'-OH cinchona alkaloid catalyst. In certain embodiments, this reaction is operationally simple and affords high enantioselectivity as well as good to excellent yield for an exceptionally broad range of alpha-keto esters.
