Description
Summary:The title molecule, C21H30N2O5, is chiral with four stereogenic centres. The crystal is a racemate and consists of enantiomeric pairs with the relative configuration rac-(6S*,7R*,8R*,9S*). The ethyl fragment of the ethoxycarbonyl group at position 6 is disordered in a 0.46 (3):0.54 (3) ratio. The crystal structure features intermolecular N—H...O. Intramolecular O—H...N and N—H...O hydrogen bonds also occur.
