title: Crystal structure of (E)-N'-{[(1R,3R)-3-isopropyl-1-methyl-2-oxo-cyclo-pent-yl]methyl-idene}-4-methyl-benzene-sulfono-hydrazide.
abstract: The title compound, C17H24N2O3S, was synthesized in order to determine the relative configuration of the corresponding β-keto aldehyde. In the U-shaped mol-ecule, the five-membered ring approximates an envelope with the methyl-ene atom adjacent to the quaternary C atom being the flap. The dihedral angles between the four nearly coplanar atoms of the five-membered ring and the flap and the aromatic ring are 38.8 (4) and 22.9 (2)°, respectively. The bond angles around the S atom are in the range 104.11 (16)-119.95 (16)°. In the crystal, mol-ecules are linked via N-H⋯O by hydrogen bonds, forming a chain along the a-axis direction.
