چکیده
In the title mol-ecule, C(15)H(12)O(3), the three five-membered rings are nearly coplanar: the dihedral angles between the cyclopentanone ring and the furan rings are 3.5 (2) and 9.7 (2)°, and the two furan rings form a dihedral angle of 7.2 (2)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds help to consolidate the crystal packing.

(2E,5E)-2,5-Bis(3,4,5-trimethoxybenzylidene)cyclopentanone
The title compound, C(25)H(28)O(7), was prepared by the base-catalysed reaction of 3,4,5-trimethoxy-benzaldehyde with cyclo-penta-none. The mol-ecule has crystallographic twofold rotation symmetry and adopts an E-configuration about the central olefinic bonds. The two benzene rings and the central cyclo-penta-none ring are almost coplanar [dihedral angle = 4.7 (2)°].
متن کاملTwo new monoterpene glycosides from Qing Shan Lu Shui tea with inhibitory effects on leukocyte-type 12-lipoxygenase activity.
We evaluated the inhibitory effect of 12 Chinese teas on leukocyte-type 12-lipoxygenase (LOX) activity. Tea catechins such as epigallocatechin gallate have been known to exhibit leukocyte-type 12-LOX inhibition. Qing Shan Lu Shui, which contains lower catechin levels than the other tested teas, suppressed leukocyte-type 12-LOX activity. To characterize the bioactive components of Qing Shan Lu S...

A novel liquid dye 2-((2E,5E)-2,5-bis(4-(methyl(2,5, 8,11-tetraoxatridecan-13-yl)amino)benzylidene)cyclopentylidene) malononitrile (TO-BDCM) was synthesized by incorporating two oligo(ethenyl glycol) groups into the backbone of a prototype malononitrile derivative (BDCM) for the purpose of increasing its solubility in organic solvents. The nonlinear absorption properties of this liquid dye on 1...
متن کاملSome p-Ranks Related to Orthogonal Spaces*
We determine the p-rank of the incidence matrix of hyperplanes of PG(n, pe) and points of a nondegenerate quadric. This yields new bounds for ovoids and the size of caps in finite orthogonal spaces. In particular, we show the nonexistence of ovoids in O10(2e), O10(3e), O9(5e), O12(5e) and O12(7e). We also give slightly weaker bounds for more general finite classical polar spaces. Another applic...
