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...
متن کامل7-Fluoro-6-nitroquinazolin-4(3H)-one
The quinazolinone unit of the title compound, C(8)H(4)FN(3)O(3), is essentially planar, with a maximum deviation of 0.0538 (14) Å for the O atom. The nitro group is twisted by 12.0 (3)° from the mean plane of the quinazolinone ring system. The crystal structure is stabilized by inter-molecular N-H⋯O, C-H⋯N and C-H⋯O hydrogen bonds.
متن کامل2-Diethylamino-6-methylpyrimidin-4(3H)-one
The title compound, C(9)H(15)N(3)O, contains four mol-ecules (A, B, C and D) in the asymmetric unit. In the crystal, the A+A and D+D pairs form inversion dimers linked by pairs of N-H⋯O hydrogen bonds. The B+C pairing is linked by the same bonds. The dimers are further linked by weak C-H⋯O inter-actions.
متن کامل2-Isopropyl-6-methylpyrimidin-4(3H)-one
The mol-ecular structure of the title compound, C(8)H(12)N(2)O, indicates that 2-isopropyl-6-methyl-pyrimidin-4-ol (the enol-form) undergoes an enol-to-keto tautomerism during the crystallization process. The pyrimidin-4(3H)-one group is essentially planar, with a maximum deviation of 0.081 (1) Å for the O atom. In the crystal structure, symmetry-related mol-ecules are linked into centrosymmeti...
متن کاملCrystal structures of 4-methoxy-6-methyl- and 4-hydroxy-6-methyl-2-pyrones.
interesting results because of the regular arrangement of the molecules in the environment.1–3 We previously reported on the photocycloaddition reaction of 4-methoxy-6-methyl-2-pyrone (1a) (Fig. 1) with maleimide (2) in the solid state to give a highly stereoselective [2 + 2] cycloadduct4 owing to the formation of two sets of 1:1 complex crystals between (1a) and (2) (Fig. 1).5 The crystal show...
