The title compound, C₁₅H₁₈N₂0, prepared from (1R,2S)-
(-)-ephedrine, crystallizes in space group P1 with two
molecules in the asymmetric unit. The oxazolidine rings
of the two molecules adopt an envelope conformation,
with the N atom 0.609 (6) and 0.623 (6)Å from the
plane of the other four oxazolidine ring atoms. Intermolecular Npyrrole--H...O and Cphenyl--H...O interactions generate a two-dimensional hydrogen-bonded network with N...O and C...O distances of 3.004 (4) and
3.051 (4)Å, respectively, and 3.599 (5) and 3.632 (5)Å,
respectively, for the two independent hydrogen-bonding
systems.
