چکیده
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.

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...

The title compound, C(21)H(23)ClN(2)O(2), was synthesized from N-amino-α-terpinene maleimide and 2-chloro-benzaldehyde. There are two independent mol-ecules in the asymmetric unit which are linked via an inter-molecular C-H⋯O hydrogen bond. The crystal studied was found to be a partial merohedral twin, with a 0.74 (7):0.26 (7) domain ratio.
