Özet

Novel phosphonate compounds were synthesized via Michael addition of N-heteroaromatic compounds to aryl-and alkyl-substituted vinylphosphonates using scandium triflate as the catalyst. Intramolecular cyclization reaction of the Michael adducts obtained gives novel (dimethoxyphosphoryl) pyrrolizin-3-ones in high yields as a single diastereomer.
