In the title compound, C(17)H(14)O(4), the C=C bond adopts an E conformation and the dihedral angle between the benzene rings is 73.9 (1)°. The crystal packing features C-H⋯O hydrogen bonds, which generate C(4) chains propagating along the b-axis direction. Weak aromatic π-π stacking inter-actions [centroid-centroid distance = 3.703 (1) Å] are also observed.

A new class of cinnamate-based light-responsive ionic liquids was synthesized and characterized, and these ionic liquids with longer alkyl chains showed a remarkable increase in ionic conductivity under UV light irradiation in aqueous solutions.

Six novel halogenated soraphen analogues have been isolated from the wild-type producing organism using precursor directed biosyntheses; the best 'delivery vehicle' for the novel starter acids was cinnamate but ortho substituents were not tolerated by the soraphen PKS.

A novel method for producing styrenes from trans-cinnamic acids was developed. When trans-cinnamic acid was incubated with plant cell cultures at room temperature, styrene was obtained. 4-Hydroxy-3-methoxystyrene (2a), 3-nitrostyrene (2f) and furan (2g) were synthesized quantitatively.

NADPH-cytochrome P450 (cytochrome c) reductase (EC 1.6.2.4) was solubilized by detergent from microsomal fraction of wounded Jerusalem-artichoke (Helianthus tuberosus L.) tubers and purified to electrophoretic homogeneity. The purification was achieved by two anion-exchange columns and by affinity chromatography on 2',5'-bisphosphoadenosine-Sepharose 4B. An Mr value of 82000 was obtained by SDS...

There are many efforts reported on finding effective catalysts for oxygen evolution reactions (OERs), which important in the energy field. Coordination polymers, including metal–organic frameworks (MOFs), attracting attention as electrocatalysts OERs due to their versatility and modulating properties. A new cobalt complex containing trans-cinnamate 2-aminopyridmidine ligands was synthesized usi...

Through the wonders of fermentation, simple sugars derived from enzymatic degradation of cellulose and hemicellulose in the plant cell wall are converted to the biofuel cellulosic ethanol, an attractive alternative to fossil fuels and grain-derived ethanol (Solomon et al., 2007). Before this fermentation takes place, however, the rigid lignin network in the cell wall must be loosened with hot a...

The electro-optical (EO) properties of poly(methyl methacrylate) and the photopolymer poly(vinyl cinnamate) doped with varying concentrations EO chromophore 2-Methyl-4-nitroaniline were measured. polymers embedded in Fabry-Pérot etalons for simultaneous determination Pockels Kerr coefficients from measurements fringe shift induced by an external electric field. It was found that host polymer ha...

One-pot, four-component procedure for the synthesis of a small library of new chiral spiro- oxindolopyrrolidines with high regio-, diastereo- (>99:1 dr), and enantioselectivity (up to 80% ee) is described. In this process, the regio- and stereochemical 1,3-dipolar cycloaddition of azomethine ylides, which were generated insitu by the reaction of isatin derivatives and sarcosin,with optically ac...
