Abstract

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.
