A chiral α-cyanovinylic sulfoxide served as an efficient chiral enophile in a Lewis acid-catalyzed intramolecular ene reaction. Use of diethylaluminum chloride as a catalyst provided extremely high stereoselectivity in the ene reaction. The stereochemistry of the ene reaction products were determined by chemical correlation and the NMR spectral analysis. A mechanistic pathway for the asymmetric induction is presented on the basis of the stereochemical results obtained.
