In the title compound, C19H16BrClO4, both the fused xanthene rings and one of the cyclo-hexane rings adopt envelope conformations, while the other cyclo-hexane ring is in a chair conformation. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming infinite chains running along [10-1] incorporating R 2 (2)(16) ring motifs. In addition, C-H⋯π inter-actions and weak π-π stacking in...

The title compound, C(20)H(20)O(5), was synthesized from the reaction between 3-methoxysalicaldehyde and 1,3-cyclo-hexa-nedione in the presence of palladium(II) chloride. The two fused xanthene rings and one of the six-membered cyclo-hexane rings adopt envelope conformations, while the other six-membered cyclo-hexane ring is in a chair conformation. The mol-ecular packing is stabilized by weak ...

In the title compound, C21H21BrClNO4, the dihydro-pyridine ring adopts a flattened boat conformation. The 3-bromo-5-chloro-2-hy-droxy-phenyl ring forms a dihedral angles of 84.44 (7)° with the dihydro-pyridine mean plane. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond, with an S(8) ring motif. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecule...
متن کامل2-Bromo-1,3-diphenylpropan-1,3-dione
The title compound, C(15)H(11)BrO(2), exists as a diketone in which the two benzoyl groups are nearly perpendicular to each other [dihedral angles = 79.9 (1) and 87.4 (1)° in the two independent mol-ecules].
متن کامل6-Bromo-1-butylindoline-2,3-dione
There are two independent mol-ecules in the asymmetric unit of the title compound, C(12)H(12)BrNO(2). The C-C bond lengths of the two carbonyl C atoms of the five-membered rings are distinctly longer than a normal Csp(2)-Csp(2) single bond. One of the mol-ecules makes parallel self-coupled (inversion) dimers by π-π inter-actions with phen-yl-phenyl inter-planar distances of 3.403 (2) Å. The oth...
