Sulfoxide-directed enantioselective synthesis of functionalized tetrahydropyridines

The highly selective base-promoted cyclization of enantiopure sulfinyl dienamines provides stereodefined sulfinyl 1,2,3,6-tetrahydropyridines (dr up to 99:1). Subsequent sigmatropic rearrangement affords tetrahydropyridin-3-ols in good yields and selectivities.Peer Reviewe
