Abstract:
The addition of synthetic (E)-anethol to the known attractant phenylacetaldehyde synergized attraction of the cotton bollworm Helicoverpa armigera, the blend invariably catching 4 to 6 times more than phenylacetaldehyde on its own. Highest catches were recorded by the 1:1-3:1 blends. The addition of salicyl aldehyde, ±linalool, (R)-(+)-limonene, 2-methoxybenzyl alcohol and 4-methoxybenzyl alcohol (compounds described earlier in the literature as co-attractants for H. armigera), increased catches when added to phenylacetaldehyde. However, the addition of these compounds did not increase catches of the (E)-anethol+pheny- lacetaldehyde blend. When directly compared with performance of the synthetic pheromone, the (E)-anethol +phenylacetaldehyde blend caught an average of 27% of the catch in pheromone baited traps. On an average 79% of moths caught in traps with the (E)-anethol+phenylacetaldehyde blend were females, while traps with pheromone caught only males. The (E)-anethol+phenylacetaldehyde blend described in this study may form the basis for the development of an efficient bisexual lure for H. armigera AFTER further optimization.

Abstract:
Phenylacetaldehyde is formed when the xenobiotic and biogenic amine 2-phenylethylamine is inactivated by a monoamine oxidase–catalyzed oxidative deamination. Exogenous phenylacetaldehyde is found in certain foodstuffs such as honey, cheese, tomatoes, and wines. 2-Phenylethylamine can trigger migraine attacks in susceptible individuals and can become fairly toxic at high intakes from foods. It may also function as a potentiator that enhances the toxicity of histamine and tyramine. The present investigation examines the metabolism of phenylacetaldehyde to phenylacetic acid in freshly prepared and in cryopreserved guinea pig liver slices. In addition, it compares the relative contribution of aldehyde oxidase, xanthine oxidase, and aldehyde dehydrogenase in the oxidation of phenylacetaldehyde using specific inhibitors for each oxidizing enzyme. The inhibitors used were isovanillin for aldehyde oxidase, allopurinol for xanthine oxidase, and disulfiram for aldehyde dehydrogenase. In freshly prepared liver slices, phenylacetaldehyde was converted mainly to phenylacetic acid, with traces of 2-phenylethanol being present. Disulfiram inhibited phenylacetic acid formation by 80% to 85%, whereas isovanillin inhibited acid formation to a lesser extent (50% to 55%) and allopurinol had little or no effect. In cryopreserved liver slices, phenylacetic acid was also the main metabolite, whereas the 2-phenylethanol production was more pronounced than that in freshly prepared liver slices. Isovanillin inhibited phenylacetic acid formation by 85%, whereas disulfiram inhibited acid formation to a lesser extent (55% to 60%) and allopurinol had no effect. The results in this study have shown that, in freshly prepared and cryopreserved liver slices, phenylacetaldehyde is converted to phenylacetic acid by both aldehyde dehydrogenase and aldehyde oxidase, with no contribution from xanthine oxidase. Therefore, aldehyde dehydrogenase is not the only enzyme responsible in the metabolism of phenylacetaldehyde, but aldehyde oxidase may also be important and thus its role should not be ignored.

Abstract:
Wastewater minimization in phenylacetaldehyde production by using indirect electrochemical oxidation of phenylethane instead of the seriously polluting traditional chemical process is described in this paper. Results show that high current efficiency of Mn(III) and high yield of phenylacetaldehyde can be obtained at the same sulfuric acid concentration (60%). The electrolytic mediator can be recycled and there will be no waste discharged.

Abstract:
A highly selective one-pot synthesis of polysubstituted isoflavanes has been developed. The reaction proceeds through the cycloaddition of methyl styryl ethers, derived from phenylacetaldehyde dimethyl acetals under acidic conditions, with electron-withdrawing ortho-quinone methides generated in situ. When phenylacetaldehyde dimethyl acetals were reacted with salicylaldehydes, the reaction proceeded smoothly to afford the corresponding isoflavanes stereoselectively in high yields and with excellent regioselectivities. The present reaction provides versatile access to functionalized isoflavanes, and constitutes a useful tool for the synthesis of biologically active molecules.

Abstract:
This work outlines the influence of Cu(II) and SO2 concentrations in Chardonnay juice or Shiraz must on the respective wine composition. Analyses were conducted pre- and post-fermentation, after cold stabilization, after bentonite treatment (Chardonnay only), at bottling, and 15 months after bottling. The quantification of total Cu was conducted by inductively coupled plasma optical emission spectrometry and free Cu by stripping potentiometry. Low molecular weight sulfur compounds, volatile aldehyde compounds, and general volatile compounds, including esters and terpenes, were quantified with gas-chromatography- or liquid-chromatography-QQQ-mass spectrometry. For Chardonnay, increased Cu concentration in the juice resulted in higher concentrations of Cu in the respective wine, while Shiraz wines showed no significant difference. Increased Cu addition to Chardonnay juice also produced significantly higher concentrations of H2S, 3-methylbutanal, and methional, but lower concentrations of methanethiol and phenylacetaldehyde, while SO2 addition increased 3-methylbutanal and phenylacetaldehyde, and decreased methanethiol production from post-fermentation to post-bottle aging. For the Shiraz, SO2 led to higher concentrations of H2S, and both SO2 and Cu addition increased the concentrations of hexanal, 3-methylbutanal, and phenylacetaldehyde in wine, but this effect diminished after cold stabilization. This study shows that SO2 and Cu in grape juice/must can have long-term implications for wine composition.

Abstract:
Tamarix has been widely used as barbecue skewers to obtain a good taste and a unique flavor of roast lamb in China. Many flavonoids have been identified from Tamarix, which is an important strategy employed to reduce the formation of heterocyclic amines (HAs) in roast meat. Isorhamnetin, hispidulin, and cirsimaritin from Tamarix ramosissima bark extract (TRE) effectively inhibit the formation of 2-amino-1-methyl-6-phenylimidazo[4,5-b] pyridine (PhIP), the most abundant HAs in foods, both in roast lamb patties and in chemical models. According to the results of the GC-MS analysis, TRE and the three flavonoids significantly reduced the contents of phenylacetaldehyde, an important intermediate involved in PhIP formation at three levels. A subsequent ultra performance liquid chromatography-mass spectrometry (UPLC-MS) analysis revealed that these flavonoids trapped phenylacetaldehyde by forming interaction adducts. The formation of three postulated adducts, 8-C-(E-phenylethenyl)isorhamnetin, 6-C-(E-phenylethenyl)isorhamnetin and 8-C-(E-phenylethenyl)hispidulin, in the chemical models and roast lamb patties was further confirmed by a TOF-MS/MS analysis. Our results demonstrate that TRE and the corresponding flavonoids trap phenylacetaldehyde to form adducts and thus inhibit PhIP formation, suggesting their great potential beneficial effects on human health.

Les années 1990 ont été marquées par le développement de la Chimie Verte avec les premiers travaux sur le sujet et l’introduction des Douze Principes. Depuis, le nombre de recherches sur la Chimie Verte n’a cessé de croître. Ces travaux de thèse portent sur le développement de méthodes de déshydratation dans le but de former des molécules à haute valeur ajoutée en utilisant les Douze Principes de la Chimie Verte en tant que ligne directrice. Deux molécules cibles ont été sélectionnées : (i) le phénylacétaldéhyde, obtenu par déshydratation du 1-phényléthane-1,2-diol, qui est utilisé dans la composition de parfums, de médicaments, d’insecticides, etc., ou en tant qu’intermédiaire réactionnel ; et (ii) le furfural, formé par la triple déshydratation du D-xylose (monomère principal des hémicelluloses), qui peut être utilisé comme solvant sélectif ou comme molécule plateforme pour produire une large gamme de composés d’intérêt. Plusieurs points-clés ont été identifiés pour concevoir des procédés de déshydratation verts: le solvant (l’eau ou le solvant éco-compatible CPME), la méthode d’activation (utilisation d’irradiation micro-ondes ou d’un réacteur en flux continu) et le catalyseur (chlorures de métaux ou résine échangeuse d’ions)
The 1990s have witnessed the development of Green Chemistry with the first researches on the subject and the introduction of the Twelve Principles. Since then, the number of scientific works on Green Chemistry has continuously grown. This PhD work focus on the development of dehydration methods to form high added value molecules by using the Twelve Principles of Green Chemistry as a guiding framework. Two target molecules were selected: (i) phenylacetaldehyde, obtained by the dehydration 1-phenylethane-1,2-diol, which is used in perfume compositions, for the preparation of pharmaceuticals, insecticides, etc., or as a chemical intermediate; and (ii) furfural, formed thanks to the triple dehydration of D-xylose (the main sugar unit of hemicellulose), which can be used as a selective solvent or as a platform molecule to produce a wide range of high-value chemicals. The optimisation of green production processes was focused on several key points: solvents (water and the eco-friendly CPME), activation method (microwave irradiation and continuous flow) and catalysis (metal chlorides and ion-exchange resin)

Neste trabalho estudou-se a obtenção da fragrância de jacinto a partir da acetalização do glicerol com fenilacetaldeído. A reação foi catalisada por carvões ativados comerciais e carvão de bagaço de cana, submetidos a tratamento ácido por meio de oxidação e/ou sulfonação. Avaliou-se as propriedades físicas e químicas dos diversos materiais carbonáceos tratados por meio das isotermas de adsorção e dessorção de nitrogênio, dessorção termo programada de amônia (TPD-NH3), infravermelho com transformada de Fourier (FTIR), espectroscopia de fotoelétrons de raios X(XPS), análise termogravimétrica (TGA), titulação de Boehm, difração de raios X e microscopia eletrônica de varredura com energia dispersiva por raios X(MEV-EDX). Os produtos cis- e trans-2-benzil-4-hidroximetil-1,3-dixolano e cis- e trans-4-benzil-5-hidroxi-1,3-dioxano, obtidos na acetalização do glicerol, foram identificados e quantificados por ressonância magnética nuclear de prótons (¹HRMN) e cromatografia em fase gasosa acoplado à espectrometria de massas (CG-MS). Os testes catalíticos realizados avaliaram a influência da concentração do catalisador, razão molar dos reagentes, temperatura e solvente no meio reacional, demonstrando rendimentos superiores aos obtidos com sólidos ácidos comerciais de alto custo. Os catalisadores CA-NS e CBCS forneceram valores de conversão próximos a 95% e seletividade de 80% e 20%, respectivamente para dioxolano e dioxano. Além disso, os catalisadores foram estáveis nas condições reacionais, não havendo indicação de lixiviação dos sítios ácidos inseridos na sua superfície.
In the present study it was investigated the production of hyacinth fragrance from glycerol acetalization with phenylacetaldehyde. The reaction was catalyzed by a commercial activated carbon and a carbon obtained from sugar cane bagasse. Solids were previously submitted to oxidation and/or sulfonation treatments. Physicochemical properties of the treated carbonaceous materials were evaluated by N2 adsorption/desorption isotherms, temperature programmed desorption (NH3-TPD), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), thermal gravimetric analysis (TGA), Boehm titration, X-ray diffraction (XRD) and scanning electron microscopy with X-ray microanalysis (SEM-EDX). The products cis and trans-2-benzyl-4-hydroxymethyl-1,3-dioxolane and cis- and trans-4-benzyl-5-hydroxy-trans-1,3-dioxane, obtained in the glycerol acetalization, were identified and quantified respectively by proton nuclear magnetic resonance (¹HRMN ) and gas chromatography coupled to mass spectrometry(GC-MS). Catalytic tests evaluated the effect of catalyst concentration, molar ratio of reactants, temperature and solvent in the reaction medium, demonstrating results better than other high-cost commercial catalysts. CA-NS and CBCS catalysts provided conversion values close to 95% and selectivities of 80% and 20%, respectively to dioxolane and dioxane. In addition, the catalysts were stable in the reaction media, with no detect able leaching of the acidic sites inserted on the solid surface.

Abstract:
Peu d'enzymes de synthèse de composés odorants sont connues chez le genre Rosa. Ce travail de thèse a permis l'identification de quelques-unes de ces protéines grâce à la technologie des puces à ADN, à l'analyse de l'expression des gènes par RT-PCR quantitative en temps réel (qPCR) et à l'analyse des parfums par chromatographie en phase gazeuse (CPG). Une puce confrontant les ADNc d'une rose parfumée à ceux d'une rose non parfumée a permis de corréler l'expression d'un gène, codant pour une Nudix hydrolase, très fortement exprimé dans la rose parfumée, avec la présence des monoterpènes dans le parfum de nombreux cultivars de rosiers. La caractérisation d'un rosier dont l'expression de ce gène est fortement réduite par ARN interférants, a permis de confirmer le rôle de celui-ci dans la synthèse des monoterpènes. La phénylacétaldéhyde synthase (PAAS) est une autre enzyme participant à la synthèse du parfum. Trois allèles de cette protéine ont précédemment été mis en évidence. Les résultats de qPCR et de CPG dans une population hybride ont permis de montrer que l'allèle a1 est le seul à pouvoir induire la synthèse et l'émission de 2-phényléthanol. Les activités respectives des différentes isoformes ont été testées in vitro chez la levure et in planta dans des feuilles de tabac et des cals de rosier : ces expériences montrent que les trois isoformes ont des activités comparables. L'absence de synthèse de 2-phényméthanol chez les plantes présentant les isoformes a2 et a3 réside donc dans la très faible expression de leurs allèles, induisant probablement une faible concentration de l'isoforme dans les cellules

2-phenylethylamine is an endogenous constituent of the human brain and is implicated in cerebral transmission. This bioactive amine is also present in certain foodstuffs such as chocolate, cheese and wine and may cause undesirable side effects in susceptible individuals. Metabolism of 2-phenylethylamine to phenylacetaldehyde is catalysed by monoamine oxidase B but the oxidation to its acid is usually ascribed to aldehyde dehydrogenase and the contribution of aldehyde oxidase and xanthine oxidase, if any, is ignored. The objective of this study was to elucidate the role of the molybdenum hydroxylases, aldehyde oxidase and xanthine oxidase, in the metabolism of phenylacetaldehyde derived from its parent biogenic amine. Treatments of 2-phenylethylamine with monoamine oxidase were carried out for the production of phenylacetaldehyde, as well as treatments of synthetic or enzymatic-generated phenylacetaldehyde with aldehyde oxidase, xanthine oxidase and aldehyde dehydrogenase. The results indicated that phenylacetaldehyde is metabolised mainly to phenylacetic acid with lower concentrations of 2-phenylethanol by all three oxidising enzymes. Aldehyde dehydrogenase was the predominant enzyme involved in phenylacetaldehyde oxidation and thus it has a major role in 2-phenylethylamine metabolism with aldehyde oxidase playing a less prominent role. Xanthine oxidase does not contribute to the oxidation of phenylacetaldehyde due to low amounts being present in guinea pig. Thus aldehyde dehydrogenase is not the only enzyme oxidising xenobiotic and endobiotic aldehydes and the role of aldehyde oxidase in such reactions should not be ignored.

Abstract:
During summer 2019, pilot tests were conducted in the Eastern part of the Krasnodar Krai and in the North of the Voronezh Region on two volatile semiochemicals of maize (phenylacetaldehyde and 4-methoxy-2-phenethyl alcohol) to monitor the European corn borer Ostrinia nubilalis number in comparison with sex pheromones. Traps with semiochemical lure caught significantly more pest adults than traps with sex pheromone – in the Voronezh Region by 16.5 times, and in the Krasnodar Krai by 2.4 times. At the same time, about half of the moths attracted by semiochemical lure were females, whose information value for forecasting is significantly higher than that of males. The results obtained indicate that semiochemical lure can be used for monitoring pests, especially in the Northern foci of its harm, where traps with sex pheromones cannot provide reliable monitoring of the insect
