title: Asymmetric tandem reactions of N-sulfonylimines and α,β-unsaturated aldehydes: an alternative reaction pathway to that of using saturated aldehydes.
abstract: An organocatalyzed asymmetric tandem reaction of cyclic N-sulfonylimines and α,β-unsaturated aldehydes was developed. These substrates follow an alternative reaction pathway to that of reactions involving saturated aldehydes, affording similar piperidine derivatives.
