(±)-syn-Isopropyl 4-(1,1,1,3,3,3-hexafluoropropan-2-yloxy)-1-hydroxy-3-methyl-2-(prop-1-ynyl)cyclopent-2-enecarboxylate
The title compound, C(16)H(18)F(6)O(4), was obtained through an unprecedented one-pot reaction sequence involving a Gosteli-Claisen rearrangement and a cyclo-isomerization. The constitution and relative configuration were determined by single-crystal X-ray diffraction analysis. In the crystal, mol-ecules are connected via O-H ⋯ O hydrogen bonds.
متن کاملSynthesis of 1-Hydroxy-2-(Prop-2'-Enyl) 9-Antrone
An efficient synthesis of the 1-hydroxy-2-(prop-2'-enyl)9-anthrone is described. Selective nitration of anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-9,10-anthraquinone in good yield as the key intermediate. Reaction with allyl bromide/K2CO3 and subsequent selective reduction accompanie...
متن کامل3-(4-Chlorophenyl)-1-(2-methyl-4-phenylquinolin-3-yl)prop-2-en-1-one
The crystal structure of the title compound, C(25)H(18)ClNO, shows that the mol-ecules are isolated and not involved in inter-molecular C-H⋯O or C-H⋯Cl inter-actions. However, the phenyl and quinoline rings are involved in π-π inter-actions [centroid-centroid distance = 3.8829 (9) Å].
متن کامل(2E)-3-(4-Bromophenyl)-1-(2-methyl-4-phenyl-3-quinolyl)prop-2-en-1-one
The conformation about the ethene bond [1.316 (3) Å] in the title compound, C(25)H(18)BrNO, is E. The quinoline ring forms dihedral angles of 67.21 (10) and 71.68 (10)° with the benzene and bromo-substituted benzene rings, respectively. Highlighting the non-planar arrangement of aromatic rings, the dihedral angle formed between the benzene rings is 58.57 (12)°.
متن کامل3-(4-Fluorophenylsulfonyl)-5-isopropyl-2-methyl-1-benzofuran
In the title compound, C(18)H(17)FO(3)S, the 4-fluoro-phenyl ring makes a dihedral angle of 82.12 (4)° with the plane of the benzofuran fragment. In the crystal structure, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
