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.
Baylis-Hillman reaction - Friedel-Crafts
reaction - intermolecular [3+2] cycloaddition - arylation - spiro compounds
