PEG-related polymer resins as synthetic supports

Abstract

Combinatorial chemistry has become a significant part of the discovery and optimization process for novel drugs, affinity ligands, and catalysts. The polymeric supports play a key role in combinatory chemistry. Therefore, various kinds of functional polymer resins have been exploited as supports, reagents, and catalysts in organic synthesis. In comparison to the conventional Merrifield resins, the poly(ethylene glycol) (PEG)-related polymer resins have advantages including good compatibilities with polar solvents, good solvent absorbency and swelling properties. This review focuses primarily on the more recent work in the field of developing PEG-related polymer resins as supports for organic synthesis. © 2010 Science China Press and Springer-Verlag Berlin Heidelberg.
