Acid Labile) is described as a new linker for the solid-phasesynthesis of peptide carboxylic acids. It is based on the electron-rich 3,4-ethylenedioxythenyl (EDOTn) moiety and allows the obtention of free and tert-butyl-protected peptides by cleavage with 90% and 0.5% TFA, respectively. This very high acid lability makes it useful for the synthesis of sensitive peptides. Free and tert-butyl-protected
