This new hydrazone resin provides a convenient method for the synthesis of peptide hydrazides, which can be applied in ligation or fragment condensation technique. It was shown that the hydrazone linker can tolerate treatment with 5 % TFA/DCM thus permitting selective removal of Mtt or related acid-labile protecting groups. The use of preloaded resins is more convenient, permits to save time and in certain cases circumvents the racemization issues.
