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...
