Homochiral metal-organic frameworks with enantiopure proline units for the catalytic synthesis of ß-lactams.

ABSTRACT

Two enantiopure organic ligands integrating flexible proline units and rigid isophthalate units have been rationally designed and employed for the construction of four homochiral porous metal-organic frameworks (MOFs), respectively. One pair of these MOFs is used as heterogeneous catalysts to construct ß-lactam derivatives by oxidative coupling reactions.
