β¦ Synopsis
An efficient method for the solid phase synthesis of aspartyl aldehyde peptides has been developed. It uses a low cost synthetic process for the preparation of Fmoc-protected Weinreb amide linker. This procedure covers several tetrapeptide aspartyl aldehydes as well as biotinylated tetrapeptide aspartyl aldehydes.

A new linker based on the dibenzosuberyl system was developed in order to synthesisΒ’ peptide Cterminal semicarbazones which can bΒ’ readily converted into peptide (7-terminal aldehydes. The method uses Fmoc-methodoiogy and proceeds with no loss of stereochemical integrity.
We describe an efficient solid-phase synthesis of C-terminal peptide aldehyde. Making use of the stability of the PAM linker towards both acid and base conditions, a pentapeptide was synthesized starting from a PAM resin according to Fmoe/tBu chemistry. The side-chains were deprotected by TFA. The p
