Ethyl 2-(4-meth­oxy­phen­yl)-6-oxa-3-aza­bicyclo[3.1.0]hexane-3-carboxyl­ate: crystal structure and Hirshfeld analysis

The title compound, C(14)H(17)NO(4), features an epoxide-O atom fused to a pyrrolidyl ring, the latter having an envelope conformation with the N atom being the flap. The 4-meth­oxy­phenyl group is orthogonal to [dihedral angle = 85.02 (6)°] and lies to the opposite side of the five-membered ring to the epoxide O atom, while the N-bound ethyl ester group (r.m.s. deviation of the five fitted atoms = 0.0187 Å) is twisted with respect to the ring [dihedral angle = 17.23 (9)°]. The most prominent inter­actions in the crystal are of the type methine-C—H⋯O(carbon­yl) and these lead to the formation of linear supra­molecular chains along the c axis; weak benzene-C—H⋯O(epoxide) and methine-C—H⋯O(meth­oxy) inter­actions connect these into a three-dimensional architecture. The analysis of the Hirshfeld surface confirms the presence of C—H⋯O inter­actions in the crystal, but also the dominance of H⋯H dispersion contacts.
