title: (4S)-Benzyl 4-isopropyl-5-oxo-1,3-oxazolidine-3-carboxyl-ate.
abstract: In the crystal structure of the title compound, C(14)H(17)NO(4), obtained by the reaction of N-benzoxycarbonyl-l-valine, paraformaldehyde and 4-methyl-benzene-sulfonic acid, mol-ecules are linked by C-H⋯O hydrogen bonds, generating linear chains parallel to the a axis. C-H⋯π inter-actions of stacked benzene rings also provide stability for the crystal structure.
