Chiral cyclohexane motif is widespread in the molecular structures of nature products and medicinal chemicals. And polysubstituted chiral cyclohexanes are important building blocks in organic synthesis. A tandem cyclization via asymmetric induction for the construction of polysubstituted chiral cyclohexane skeletons is described. In the presence of phase-transfer-catalyst, optically active γ-nitro ketone reacted with chalcone smoothly to afford cyclohexane skeletons bearing five consecutive stereocenters in 40%~71% yields with 90%~98% ee. It should be noted that the scope of chalcone is broad. Especially, the asymmetric induction is kept at a high level in each step of the tandem cyclization reaction.
