Dual Role of Vinyl Sulfonamides as N‐Nucleophiles and Michael Acceptors in the Enantioselective Synthesis of Bicyclic δ‐Sultams

A new methodology for the synthesis of enantiomerically enriched bicyclic δ‐sultams is described, involving an initial organocatalytic intramolecular aza‐Michael reaction of vinyl sulfonamides bearing a conjugated ketone at a remote position. The resulting Michael adducts were then subjected to an i...
