Crystal structure of cholest-5-en-3β-yl 3-(2,4-dimethoxy-3-methylphenyl)prop-2-enoate
In the title compound, C39H58O4, the steroid rings A and C adopt a chair conformation, while ring B adopts a half-chair conformation, and ring D has an envelope conformation, with the methyl-substituted C atom as the flap. In the crystal, mol-ecules pack within layers parallel to (100), with their long axis parallel to the [101] direction. Adjacent layers are linked via C-H⋯O hydrogen bonds and...
متن کاملCrystal structure of methyl (E)-4-[2-(8-hydroxyquinolin-2-yl)vinyl]benzoate
The title compound, C19H15NO3, was synthesized by a Perkin reaction of 2-methyl-8-hy-droxy-quinoline and 4-formyl-2-methyl-benzoate in acetic anhydride under a nitro-gen atmosphere. The mol-ecule has an E conformation about the C=C bond, and the quinoline ring system and the benzene ring are inclined to one another by 29.22 (7)°. There is an intra-molecular O-H⋯N hydrogen bond in the 8-hy-droxy...

In the title compound, C(13)H(10)BrN(3)O(3), the pyrimidine and benzene rings are twisted with an inter-planar angle of 58.4 (1)°. The secondary amide group adopts a cis conformation with an H-N-C-O torsion angle of 14.8 (1)°. In the crystal, mol-ecules are connected into inversion dimers via pairs of N-H⋯N hydrogen bonds, generating an R(2) (2)(8) motif. The dimers are further connected throug...
متن کاملCrystal structure of benzyl 3-oxo-2-oxa-5-azabicyclo[2.2.1]heptane-5-carboxylate
The title compound, C13H13NO4 (also known as N-benzyl-oxycarbonyl-4-hy-droxy-l-proline lactone), crystallizes with two mol-ecules in the asymmetric unit. They have slightly different conformations: the fused ring systems almost overlap, but different C-O-C-C torsion angles for the central chains of -155.5 (2) and -178.6 (2)° lead to different twists for the terminal benzene ring. In the crystal...
