Abstract: The title compound, C16H17NO3, crystallizes in the space group P, with one molecule in the asymmetric unit. The amide H atom is engaged in an intramolecular N-HO contact to the O atom of one of the two carbonyl groups. The molecules form centrosymmetric dimers through self-complementary C-HO hydrogen-bonding interactions defining the R22(14)[R21(6)] motif. The supramolecular structure is achieved by aryl C-H interactions, as well as face-to-face - stacking interactions between lactone and benzenoid rings.
