6-(2-Hydroxyanilinomethylene)-4-nitrocyclohexa-2,4-dien-1-one
The molecule of the title compound, C(13)H(10)N(2)O(4), is nearly planar with a dihedral angle between the two aromatic rings of 2.24 (9)°. The NH group forms an intramolecular hydrogen bond with the carbonyl O atom. The mol-ecules form dimers about inversion centers in the crystal structure via inter-molecular O-H⋯O hydrogen bonds.

wide interest because the 1H-pyridin-2-ones obtained in this process are versatile synthetic building blocks in the synthesis of alkaloids.1–5 The title compound, (–)-(1′R)-1-(2′-hydroxy-1′-phenyl-ethyl)1H-pyridin-2-one II, was prepared by stirring a solution of pyridinium salt, I (4.0 mmol), in water (25 ml) and cooled to 5 ̊C (Scheme 1). A solution of K3Fe(CN)6 (11 eq.) in water (30 ml) was ad...
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 کامل(6Z)-4-Bromo-6-{[(2-hydroxyethyl)amino]methylidene}cyclohexa-2,4-dien-1-one
The title mol-ecule, C(9)H(10)BrNO(2), excluding methyl-ene H atoms and the C-OH group, is essentially planar, with a maximum deviation of 0.037 (2) Å for the N atom. The N-C-C-O torsion angle is -63.1 (3)°. The mol-ecular structure is stabilized by a weak intra-molecular N-H⋯O(carbonyl) hydrogen bond, forming an S(6) motif. In the crystal, mol-ecules are linked by O-H⋯O and C-H⋯O hydrogen bond...
متن کامل(E)-3-(2,3-Dimethoxyphenyl)-1-(2-hydroxy-4-methoxyphenyl)prop-2-en-1-one
The mol-ecular conformation of the title compound, C(18)H(18)O(5), is stabilized by a strong intra-molecular hydrogen bond between the hydroxyl and carbonyl groups. The C=C double bond displays an E configuration while the carbonyl group shows an S-cis configuration relative to the double bond. The dihedral angle between the two rings is 15.0 (1)°.
