Summary The phenolic hydroxyl groups in the lignin model compounds, 2-methoxy-4-propylphenol and 4-hydroxy-3-methoxyacetophenone, were removed by first converting the hydroxyl groups to the trifluoromethanesulfonates (triflates) and then cleaving the triflate substituents via catalytic hydrogen transfer. The products, 1-methoxy-3-propylbenzene and 3-methoxyacetophenone, were characterized by 1H and 13C NMR, mass spectrometry and elemental analyses. The effect of the removal of the phenolic groups on the photostability of the model compounds was evaluated by impregnating the compounds into What

Abstract:

Biotransformation of paeonol (1) with the white-rot basidiomycete Coriolus versicolor afforded two metabolites, 2,4-dihydroxyacetophenone (2) and 2,5-dihydroxy-4-methoxyacetophenone (3), which were identified by spectroscopic methods. Compound 3 showed higher antioxidative, antibacterial, antifungal activities than 1 or 2. The results demonstrate for the first time that C. versicolor has the capacities to catalyze hydroxylation and demethylation reactions on the aromatic compound.

Synthetic approaches towards the synthesis of the pyrrole oxazole skeleton of phorbazoles A–D are described. An efficient synthesis of the pyrrole oxazole skeleton (19) from pyrrole and 4- methoxyacetophenone was developed. In the key step, cyclodehydration of the amide (16) resulted in formation of the diprotected pyrrole oxazole (17). Subsequent deprotection of the diprotected pyrrole oxazole (17) gave the target phorbazole skeleton (19).

The effects of PW/SiO2activation temperature on MPA (p-methoxyacetophenone) synthesis from toluene and acetic anhydride were carefully studied, and catalysts were carefully characterized by BET and XRD.

The weak acid site PW12O38.5over PW/SiO2came into being when activation temperature increased to 300 °C, and the appearance of PW12O38.5over PW/SiO2resulted in MPA yield decline.

Abstract:

The purpose of this research is to develop the synthesis of chalcone through a green chemical approach that has the potential as an antibacterial. Chalcone synthesis was carried out using a grinding technique through a Claisen-Schmidt condensation reaction at room temperature for 30 minutes by grinding benzaldehyde (4-bromobenzaldehyde or 4- hydroxybenzaldehyde), 4'-methoxyacetophenone, and NaOH. The reaction product was purified by recrystallization through 96% ethanol. The purity of the compound was tested by TLC. Characterization of chalcones by FT IR, 1HNMR, 13C-NMR, and GC-MS showed that

Abstract:

Multimetallic nanocatalysts have remarkably revealed activities in various catalytic applications. Herein, the ternary nanocatalysts based on palladium-vanadium-cobalt were successfully synthesized through the reduction of their salts with sodium borohydride including impregnating of activated carbon (AC) substrate with colloid solution of metallic nanoparticles (PdVCo/C). The immobile of trimetallic PdVCo on AC was evidenced by XRD, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and UV-VIS spectroscopy. TEM imaging showed that the PdVCo particles size is about 7 nm

Abstract:

Analysis of aromatic compounds in the New Zealand manuka honey was carried out by solid phase microextraction followed by gas chromatography-mass spectrometry. A total of 38 compounds were detected. Seven of them such as; 1,4-bis(x-methoxyphenyl)-but-2-en-1-one, 1,5-bis(x-methoxyphenyl)-pent-3-en-1-one, 1,4-bis(x-methoxyphenyl)-1-pentanone, 1,6-bis(x-methoxyphenyl)-3-heptene, 1,6-bis(x-methoxyphenyl)-hex-2(3 or 4)-en-1-one and 2(3, 4 or 5)-hydroxy-1,6-bis(x-methoxyphenyl)-1-hexanone, had never before been identified as natural products. Their structures were deduced from the mass spectral data

Abstract:

Phytochemical study on the methanolic extract of the aerial parts of this plant led to the isolation of 7 phenolic compounds (1-7), including 3 new ones (1-3). Their chemical structures were determined to be (7,8- threo)-1 -O-β-D-[6′ -O-syringoylglucopyranosyl]-2-methoxy-7,8,9-trihydroxyphenylpropane (1), (7,8- threo)-8 -O-(2′′-methoxyacetophenone-1′′-yl)-1 -O-β-D-glucopyranosyl-2-methoxy-7,9-dihydroxyphenylpropane (2), 1 -O-β-D-glucopyranosyl-2 -O-(2′′-methoxy-4′′-acetylphenyl)-3-hydroxypropane (3), (−)-isolariciresinol 4 -O-β-D-glucopyranoside (4), (−)-isolarisiresinol 9′ -O-β-D-glucopyranos

The nature of the solubilization of β-phenyl-4-mefhoxypropiophenone (1) in the nematic and crystal-B liquid crystalline phases of trans,trans-4′-butyl-(1, 1′-bicyclohexyl)-4-carbonitrile (CCH-4) has been investigated by deuterium nmr spectroscopy. This has been carried out using deuterium quadrupolar splitting (ΔvQ) and T1 measurements on 1–15 mol% solutions of two selectively deuterated derivatives of the ketone in CCH-4 over the 25–110 °C temperature range. The nmr studies have been supplemented with differential scanning calorimetry (DSC) and thermal microscopic investigations of variously
