Abstract: The title compound, C₁₈H₂₃NO₅, is a potential potent new herbicide containing the pyrrolidine-2,4-dione ring system. In the crystalline state, the molecular skeleton contains one enol grouping, which is intramolecularly hydrogen bonded to a neighbouring keto O atom. The dihedral angle between the six-membered ring formed by the enol group and the benzene ring is 41.29 (10)°.
