title: 3-Cyclo-propyl-1-(4-methyl-phenyl-sulfon-yl)piperidine-3,5-diol.
abstract: In the title compound, C(15)H(21)NO(4)S, both hy-droxy groups on the piperidine ring are located in axial positions, whereas the tosyl group and the cyclo-propane ring are in equatorial positions. An intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, mol-ecules form inversion dimers via pairs of O-H⋯O hydrogen bonds, generating cyclic R(4) (4)(8) motifs, as noted previously in related diols.
