Microwave-assisted solid phase peptide synthesis on high loaded resins

Abstract

Kinetic of diffusion of reactants from the solution into the resin beads is a key factor of the efficiency of reaction in solid phase synthesis. We demonstrated in this paper that stirring is required to obtain homogeneous solution during the short coupling steps in microwave-assisted SPPS. Different types of resin, loading rate and coupling reactants were investigated to highlight this observation. © 2008 Springer Science+Business Media, LLC.
