## Abstract The standard __p__‐MBHA resin used during Boc‐chemistry synthesis of peptides carrying __C__‐terminal carboxamides is compromised by batch‐to‐batch variations in its performance. This can cause artificially ‘difficult’ couplings during peptide chain assembly, which may ultimately lead t

✦ Synopsis
A tartaric acid-based linker was elaborated on an amino PEGA resin for the synthesis of C-terminal cx-oxoaldehydes. A solid phase periodic oxidation allowed the formation of the glyoxylyl moiety and the separation of the final product from the solid support.

A new linker based on the dibenzosuberyl system was developed in order to synthesis¢ peptide Cterminal semicarbazones which can b¢ readily converted into peptide (7-terminal aldehydes. The method uses Fmoc-methodoiogy and proceeds with no loss of stereochemical integrity.
