The asymmetric unit of the title compound, C(19)H(12)O(5), contains two independent mol-ecules, both slightly buckled along an axis passing through the C=O bonds of the anthraquinone ring system (r.m.s. deviation of non-H atoms = 0.082 and 0.148 Å): the benzene rings are twisted to each other by 4.3 (3)°in one mol-ecule and 10.6(3)° in the other. In both mol-ecules, the hy-droxy group forms an ...

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...

3-Acyl-5-( 1 -am inoalkylidene)-4-hydroxy-2 Hpyran-2,6(3 //)-d ione derivatives carrying lipophilic am ino groups were found to be highly potent inhibitors o f photosynthetic electron transport, and bo th the acyl and the am inoalkylidene groups on the pyran ring appeared to be indispensable for high activity. The structural features needed for activity in the 3-acyl-5(l-am inoalkylidene)-4-hyd...

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...
