A dramatic enhancement of the diastereo- and enantioselectivity in the nitro-Michaeladdition reaction organocatalysed by a commercially available alpha,alpha-L-diaryl prolinol was disclosed when performing the reaction in unconventional hexafluorobenzene as a medium. DFT calculations were performed to clarify the origin of stereoselectivity and the role of C(6)F(6).
