In the title compound, C 18 H 33 N 3 Si 2 , the central diketiminate system is essentially planar. A short intramolecular hydrogen bond involving the imine N atoms forms a pseudo-sixmembered ring.
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
The crystal structure of the title compound, C~36~H~40~N~2~O~2~, has been determined at 173 (2) K. The molecule has __C__ ~2~ symmetry and the asymmetric unit contains one half-molecule. An intramolecular O—H...N hydrogen bond is formed between the phenol OH group and the Schiff base N atom.
