3-Hydroxy-2-[(2-hydroxy-4,4-dimethyl-6-oxocyclohex-1-en-1-yl)(thiophen-3-yl)methyl]-5,5-dimethylcyclohex-2-en-1-one
The asymmetric unit of the title compound, C(21)H(26)O(4)S, consists of two independent mol-ecules. In both mol-ecules, intra-molecular O-H⋯O hydrogen bonds stabilize the mol-ecular structure. In the crystal, each mol-ecule and its symmetry-related mol-ecule by twofold rotation form a dimer through a pair of inter-molecular C-H⋯O hydrogen bonds. In one of the mol-ecules, the thio-phene group is...
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 کامل5-Hydroxy-1-(3-hydroxy-2-naphthoyl)-3,5-dimethyl-2-pyrazoline
In the title mol-ecule, C(16)H(16)N(2)O(3), intra-molecular O-H⋯O hydrogen bonds influence the mol-ecular conformation. Inter-molecular O-H⋯O hydrogen bonds [O⋯O = 2.922 (2) Å] link the mol-ecules into centrosymmetric dimers. Weak inter-molecular C-H⋯O inter-actions assemble these dimers into layers parallel to the bc plane.
متن کامل(2E)-3-(3-Benzyloxyphenyl)-1-(2-hydroxy-5-methylphenyl)prop-2-en-1-one
In the mol-ecule of the title compound, C(23)H(20)O(3), an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. The central benzene ring makes dihedral angles of 80.17 (8) and 16.99 (7)°, respectively, with the benz-yloxy and hy-droxy-methyl phenyl rings. In the crystal, mol-ecules are linked via inter-molecular C-H⋯O hydrogen bonds to form dimers. The dimers are connected by C-H⋯O hydro...
متن کامل1-Acetyl-3-ferrocenyl-5-(2-nitrophenyl)-2-pyrazoline
In the title compound, [Fe(C(5)H(5))(C(16)H(14)N(3)O(3))], the pyrazoline ring and the substituted cyclo-penta-dienyl ring are nearly coplanar, with a dihedral angle of 8.17 (2)°, while the nitro-substituted benzene ring is twisted out of the pyrazoline ring plane by 70.76 (1)°. The mol-ecules in the crystal structure are held together by three inter-molecular C-H⋯O hydrogen bonds. There is als...
