  3,2-Hydroxypyridinone (3,2-HOPO) vinyl sulfonamide and acrylamide linkers: aza-Michael addition reactions and the preparation of poly-HOPO chelators

  摘要：

  The HOPO vinyl sulfonamide 3 and the corresponding HOPO acrylamide 10 were easily prepared by short synthetic sequences. Investigation of the aza-Michael reactions of these linkers showed that they proceed at a higher rate in solvent systems containing water. The scope and limits of the aza-Michael reactions of 3 and 10 were examined. Reagents 3 and 10 reacted cleanly with piperazine to give the corresponding adducts which were deprotected to give the di-HOPO ligands 7 and 16. Reaction of HOPO acrylamide 10 with 1,4,7-triazacyclononane gave the tris-adduct 17 which was deprotected to give the desired tris-HOPO ligand 18. Overall, the aza-Michael reactions of 3 and 10 appear to be governed not only by the solvent but also by the nature of the amine and the solubility of the reaction intermediates.
