An efficient desymmetrizing carbonyl-ene reaction of 1-substituted 4-methylenecyclohexanes with glyoxal derivatives was thus executed by a chiral N,N′-dioxide/NiII catalyst, providing facile access to cyclohexene derivatives bearing two remote 1,6-related stereocenters. This distal stereocontrol methodology originates from the efficient interaction between the catalyst with enophiles, discrimination of the two chair conformations of olefinic components, and the intrinsic six-membered transition-state structure of ene process.

The enthalpy profile for the equilibrium 1 ->//-1).The observation of a nonconcerted path for the equilibrium 1 ->/- 3 is important with respect to the understanding of the controlling factor of the concerted and nonconcerted path of a reaction.The existence of a favourable potential energy path obviously is not of prime importance. - Keywords: Diradicals / Oxygen trapping / Energy well / Supercritic fluid reactions
