Crystal structure of (E)-N′-{[(1R,3R)-3-isopropyl-1-methyl-2-oxocyclopentyl]methylidene}-4-methylbenzenesulfonohydrazide
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 aroma...

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 C atom adjacent to the quaternary C atom being the flap, and the methyl and isopropyl substituents lying to the same side of the ring. The dihedral angles between th...
متن کاملN-Isopropyl-3-methyl-2-nitrobenzamide
In the title compound, C(11)H(14)N(2)O(3), the bond lengths and angles are within normal ranges. Weak inter-molecular N-H⋯O inter-actions link the mol-ecules into chains along the a axis. A non-classical intra-molecular C-H⋯O inter-action (nitro O atom and a H atom of the nearest methyl group) is found, forming a six-membered ring with a twisted conformation. This six-membered ring has a twiste...
متن کاملCrystal structure of isopropyl 2-hydroxy-2-phenylacetate: a pharmacopoeia reference standard
The title compound, C11H14O3, is used as a pharmacopoeia reference standard for determining impurities in the drug Pregabalin, used for the treatment of epilepsy and diabetic neuropathic pain. The mol-ecule is far from being planar, with the dihedral angle between the planes of the aromatic ring and the carboxyl fragment (O-C=O) being 76.1 (6)°. The isopropyl substituent is located in a synperi...
متن کاملCrystal structure of (E)-2-[(2S,5R)-2-isopropyl-5-methylcyclohexylidene]hydrazine-1-carbothioamide
The title compound, C11H21N3S, consists of a menthone moiety attached to an extended thio-semicarbazone group with the N-N-C-N torsion angle being 11.92 (16)°. The cyclo-hexane ring has a chair conformation and the conformation about the C=N bond is E. In the crystal, mol-ecules are linked via pairs of N-H⋯S hydrogen bonds, forming chains along the a axis. The absolute structure could be assign...
