Acetophenone-based linker for solid-phase peptide synthesis.
A new and cost-effective linker for the generation of carboxylic acid end groups on Multipin supports (SynPhase crowns) has been developed. Synthesis of the linker was based on modification of grafted polystyrene (PS) crowns to generate a hydroxyethyl moiety which is acid labile in 10-20% trifluoroacetic acid (TFA) in dichloromethane (DCM). Solid-phase syntheses of model decapeptides using this linker are described.
