The title compound, C 27 H 39 N 3 O 9 , is a key intermediate in the synthesis of novel -turn mimetics based on electrophilic amination of enantiomerically pure (S)-pyroglutamic acid. The molecule adopts an extended conformation which is not stabilized by either intra-or intermolecular hydrogen bond
