ChemInform Abstract: Design of Main‐Chain Polymer of Chiral Imidazolidinone for Asymmetric Organocatalysis Application.

Abstract

Chiral imidazolinones are incorporated into the main‐chain of the polymer by ionic bonding.

Synthesis of Main-Chain Chiral Quaternary Ammonium Polymers for Asymmetric Catalysis Using Quaternization Polymerization

“…In addition of these polymer-immobilized chiral quaternary ammonium salts, we have recently developed main-chain chiral polymers with chiral organocatalysts [ 40 , 41 , 42 , 43 , 44 , 45 ]. Some useful polymerization techniques such as etherification polymerization [ 40 ], ion exchange polymerization [ 41 , 42 , 43 , 44 ], and neutralization polymerization [ 45 ] were used for the synthesis of main-chain chiral polymers with chiral organocatalysts. Interestingly, some main-chain chiral polymers showed higher enantioselectivity than the corresponding monomeric catalysts.…”
