(5S,6R)-6-Bromo-6-methyl-5-phenyl-3,4,5,6-tetra-hydro-2H-cyclo-penta-[b]pyran-7-one.

ABSTRACT: The title compound, C(15)H(15)BrO(2), was synthesized by a Brønsted acid-catalysed domino electrocyclization-halogenation reaction. The five-membered ring is essentially planar (r.m.s. deviation 0.006?Å) and forms a dihedral angle of 72.7?(3)° with the attached phenyl ring. The six-membered heterocycle adopts a half-chair conformation. The crystal packing is stabilized by a C-H?O contact.

Project description:The thio-pyran unit of the title mol-ecule, C(17)H(15)ClO(2)S, is in chair form. A crystallographic mirror plane bis-ects the mol-ecule, passing through the O=S and the opposite C=O atoms of the central ring, with statistical disorder of the Cl atom. The geometry around the S atom is tetra-hedral and the carbonyl C is planar. The 4-chloro-phenyl group at the 2 position and the phenyl ring at the 6 position have equatorial orientations. Inter-molecular C-H⋯O and C-H⋯Cl hydrogen bonds are found in the crystal structure. In addition, there is a short O⋯C inter-molecular contact [2.970 (5) Å].

rac-2-Methyl-3,4,5,6-tetra-hydro-2H-2,6-methano-1,3-benzoxazocin-4-one.

Project description:The title compound, C(12)H(13)NO(2), represents a conformationally restricted 2-pyridone analogue of 1,4-dihydro-pyridine-type calcium antagonists and was selected for a crystal structure determination in order to explore some aspects of drug-receptor inter-action. In the mol-ecule, two stereogenic centres are of opposite chirality, whereas a racemate occurs in the crystal. It was found that the formally aminic N atom of the heterocycle is essentially sp(2)-hybridized with the lone-pair electrons partially delocalized through conjugation with the adjacent carbonyl bond. As a result, the central pyridone ring assumes an unsymmetrical half-chair conformation. The critical 4-phenyl ring is fixed in a pseudo-axial and perpendicular orientation [dihedral angle 85.8?(1)°] with respect to the pyridone ring via an oxygen bridge. In the crystal a pair of centrosymmetric N-H?O hydrogen bonds connect mol-ecules of opposite chirality into a dimer. The dimers are packed by hydrophobic van der Waals inter-actions.

The ring of the 2,4-dichloro-phenyl substituent is nearly perpendicular [85.89?(4)°] to the xanthene ring system.

Project description:The molecule of the zwitterionic title compound, C(6)H(9)NO(4)S, which lies on a mirror plane, shows a puckered chair conformation of the six-membered ring with the S and N atoms out of the mean plane of the other four C atoms by 0.929?(2) and 0.647?(2)?Å, respectively.
