Ethyl 2,5-di-tert-butyl-5-eth­oxy-4-oxo-4,5-di­hydro-1H-pyrrole-3-carboxyl­ate

The title compound, C₁₇H₂₉NO₄, contains a chiral center and crystallizes as a racemate. The asymmetric unit consists of two non-equivalent mol­ecules, in which the carbeth­oxy groups have markedly different orientations [C(=O)CC(OEt)=O torsion angles = 59.3 (2) and 156.0 (2)°]. In the crystal, mol­ecules form chains along [101] through N—H...O hydrogen bonds.
