Ramage Amide Linker

05/02/2024

This Ramage's dibenzocycloheptadiene Linker is attached to aminomethylated polystyrene or amino TentaGel®. After Fmoc removal the resin can be acylated and used in Fmoc SPPS. The linker is essentially more acid sensitive than the Rink amide or PAL linker. Therefore, peptide amides can be cleaved with 3% TFA in DCM and thus it's possible to release acid sensitive peptides or protected peptide fragments.
