Abstract: The title molecule, C23H26N2O8, was synthesized in three steps starting from m-nitrocinnamic acid. The central oxazolidine ring adopts an almost perfect envelope conformation with the O atom as the flap [puckering parameter = 0.3 (6)°]. The dihedral angle formed by the benzene rings is 61.81 (9)°. In the crystal, molecules are connected into double chains parallel to  by C-HO hydrogen bonds. The absolute configuration was assigned from the synthetic procedure.
