Crystal structure of O-benzyl-L-tyrosine N-carb­­oxy anhydride

In the title compound, C17H15NO4 (alternative name; O-benzyl-L-tyrosine N-carb­oxy anhydride), the oxazolidine ring is planer, with an r.m.s. deviation of 0.039 Å. The benz­yloxy and benzyl rings are almost coplanar, making a dihedral angle of 0.078 (10)°, and are inclined to the oxazolidine ring by 59.16 (11) and 58.42 (11)°, respectively. In the crystal, mol­ecules are linked by N—H⋯O and C—H⋯O hydrogen bonds, forming ribbons propagating along [010]. The ribbons are linked by C—H⋯π inter­actions, forming a three-dimensional supra­molecular structure. The oxazolidine rings of adjacent ribbons are arranged into a layer parallel to the ab plane. This arrangement is favourable for the polymerization of the compound in the solid state.
