5-[(3-Fluorophenyl)(2-hydroxy-6-oxocyclohex-1-en-1- yl)methyl]-6-hydroxy-1,3-dimethylpyrimidine-2,4(1H, 3H)-dione
5-[(3-Fluorophenyl)(2-hydroxy-6-oxocyclohex-1-en-1-yl)-methyl]-6-hydroxy-1,3-dimethylpyrimidine-2,4(1H,3H)-dione 3 was synthesized via a multicomponent reaction. The Aldol–Michael addition reactions of N,N-dimethylbarbituric acid, cyclohexane-1,3-dione, and 3-fluorobenzaldehyde in aqueous solution gave the product in high yield. The molecular structure of the compound was confirmed by spectrosc...

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 and Biological Evaluation of 4-hydroxychromenyl arylmethyl-6-hydroxy pyrimidine-2, 4-dione Derivatives
Background: An efficient, promoted tri-component catalytic reaction between barbituric acid (or N,N-dimethyl barbituric acid), 4-hydroxy coumarin, and a wide range of aryl aldehydes using zinc oxide nanowires (ZnO NWs) to obtain some new 4-hydroxychromenylarylmethyl-6-hydroxypyrimidine-2,4-diones is described. Method: The reactants were successfully condensed ...

A novel compound involved in the aroma of the fruit Campomanesia lineatifolia was isolated; the structure was determined by spectroscopic methods, mainly 1D and 2D NMR.
متن کاملX-ray Charge-Dens Study of 5-Chloro-8-hydroxy-6-methyloaphthalene-l.4-dione: A Hydroxynaphthoquinone Derivative
The X-ray charge density analysis of a hydroxynaphthoquinnne derivative was obtained by multipolar Hansen-Coppens formalism refinement through high resolution X-ray diffraction data at 100(1) K. The molecularproperties of the title compound resulted from the combined experimental and the quantum theory of atoms inmolecules (QTAIM) studies. The topological properties of the covalent bonds and of...
