'Bottom-up' embedding of the J?rgensen-Hayashi catalyst into a chiral porous polymer for highly efficient heterogeneous asymmetric organocatalysis

摘要

The only way is up! "Bottom-up" construction of a robust chiral porous polymer (JH-CPP) embedded with the J?rgensen-Hayashi catalyst (JH) has been successfully achieved for highly efficient heterogeneous organocatalysis. The high BET surface area, wide openings and interconnected nanopores of JH-CPP increase the accessibility of catalytic sites and as such the catalyst shows excellent activity in catalyzing the asymmetric Michael addition reaction (see scheme).
