Abstract: The title compound, C₁₃H₁₈N₂O₂, is an N₄-isopropyl-L-phenylalanine-based oxadiazinanone. Although the two molecules in the asymmetric unit are oriented appropriately for hydrogen bonding, the distance between the donor and acceptor atoms is large enough to support only weak, if any, hydrogen bonding. The absolute configuration is known based on the known starting compounds in the synthetic procedure.
