An effective chiral Lewis acid-catalyzed asymmetric Baylis−Hillman reaction is described. Goodto high enantioselectivities were obtained using 3 mol % chiral catalyst. Novel camphor-deriveddimerized ligands were prepared from the condensation of (+)-ketopinic acid with the correspondingdiamines and hydrazine under acidic conditions. When α-naphthyl acrylate was used as a Michaelacceptor, the reaction is complete within 20 min with high stereoselectivity and in reasonablechemical yields.
