A general and simple protocol for the arylation of Baylis-Hillman adducts derived from nitroolefins leading to novel classes of (E)-2-nitro-1,3-diarylprop-1-enes and 1-[(E)-2-nitro-3-arylallyl]naphthalenes via an intermolecular Friedel-Crafts reaction have been achieved. Further application of these compounds has been demonstrated for the synthesis of pyrrolidines and 3-spiropyrrolidines which are integral components of many natural products and bioactive molecules.
