The chiral title compound, C 8 H 9 NO 4 , crystallizes in the noncentrosymmetric space group P2 1 2 1 2 1 , but in the absence of an atom with significant anomalous dispersion, the absolute configuration could not be determined. The H atoms in both methyl groups are eclipsed with respect to the C O

## Abstract The spectra of Δ^3^‐ and Δ^4^‐pyrrolin‐2‐one were analysed and the sign of all the coupling constants determined by tickling and triple resonance experiments. A positive allylic interaction (__J__~xz~ in **2**) is reported and four‐bond couplings are discussed in particular. Deuterium e
