摘要：
The reactivity of -nitro ketones with trifluoromethyl aldimines has been studied for the first time. Whereas under nitro-Mannich conditions only the facial stereoselectivity can be controlled, organocatalysed Mannich-type reactions allowed complete control of the absolute and relative stereoselectivity, leading to highly functionalised -amino--nitro--(trifluoromethyl) compounds as diastereomerically pure compounds. The structures of the reactants play a key role in the geometrical and/or facial stereoselectivity.
