A new and straightforward synthesis of the C-1-C-7 core fragment of nhatrangin A was achieved in 14 steps from achiral 3-hydroxybenzaldehyde, without the need of chiral reagents or enzymatic resolution to introduce the chiral centers. The key asymmetric steps include in particular a highly enantioselective organocatalyzed Michael addition on an aryl vinyl ketone, a Sharpless asymmetric epoxidation and a subsequent regioselective ring opening of the resulting chiral epoxide. This work represents the first formal enantioselective synthesis of nhatrangin A.

This study was intended to characterize six types of commercial smoked chicken products in China by using gas chromatography-mass spectrometry (GC-MS), odor-activity values (OAVs), and sensory evaluation. Results demonstrated that a total of 89 components were identi?ed in all samples, and 34 were considered as odor-active compounds because their OAVs were greater than one. Liaocheng Chicken that smoked with fruit tree sawdust had more phenols, which contributed to the smoky aroma. Jinshan and Goubangzi Chicken that smoked with sugar had more furans which contributed the overall odor with sweety and caramel aroma. Zhuozishan and Laoting Chicken that smoked with sugar and wood chips had similar flavor and volatile compounds. Tengqiao Chicken that smoked with sugar, tea and rice had significant difference with other chicken in smoky, bittern and caramel aroma (P< .05). The diversity of these smoked chicken flavors was mainly due to the cooking culture differences.

A visible-light-induced carbonylation of indoles with phenols for the synthesis of indole-3-carboxylates has been developed. The reaction proceeded via a radical carbonylation process in which elementary I-2 was used as an effective photosensitive initiator and, thus, avoided the use of transition metal catalysts. A series of different aryl indole-3-carboxylates were prepared in moderate to good yields. The broad applicability of this methodology was further highlighted by the late-stage functionalization of several phenol-containing natural products and pharmaceuticals.

Coumarins and their synthetic derivatives are extensively used as base chemicals in diverse industrial applications in the fields of pharmaceutics, cosmetics, and agrochemicals, among others. Due to the growing number of applications, the need for new methods of coumarins synthesis has gained importance worldwide. In this sense, the use of propylsulfonic acid supported in FDU-5 (FDU-5-Pr-SO3H) as a catalyst for the synthesis of coumarins via Pechmann condensation in solvent free medium was investigated. FDU-5-Pr-SO3H was synthesized by co-condensation of MPTES and TEOS. FDU-5-Pr-SO3H was used as catalyst for the synthesis of 7-hydroxy-4-methylcoumarin and reaction conditions were optimized. The optimization process involved the study of the influence of the catalyst load, Resorcinol:EAA molar ratio, reaction temperature and reaction time. The optimal conditions were: catalyst load of 1.65 mol %, reactants molar ratio of 1:1.5, temperature 130 degrees C and 60 min of reaction time. Under these conditions, the FDU-5-Pr-SO3H material showed excellent yield (96.5%) and turn over frequency (59 h(-1)). Finally, the synthetized material was assessed as a catalyst with other phenolic compounds with ethyl acetoacetate and with ethyl benzoylacetate. The obtained products were isolated and identified by comparison of their spectral data with those reported in literature; from these results can be concluded that the catalyst is active with a wide range of phenolic substrates.

Bifunctional catalysts comprised of both noble metal and Bronsted acid sites are of growing interest for many reactions, such as the hydrodeoxygenation (HDO) of oxygenates produced by the deconstruction of lignocellulosic biomass. One method of preparing a bifunctional metal-acid catalyst is to modify the supporting material of a metal catalyst with acid-containing ligands, such as phosphonic acids (PAs), which provide tunable Bronsted acid sites at the metal-support interface. Here, we explore the potential for PA modification to improve HDO rates on Al2O3, TiO2, CeO2, and SiO2-Al2O3 supports. PAs containing either alkyl or carboxylic acid (CA) tails were used to modify Pt catalysts on each support. PA modification improved HDO rates for the model compound benzyl alcohol when applied to Pt supported by Al2O3, TiO2, and CeO2, but had a negative effect on the HDO rate of Pt/SiO2-Al2O3. Measurements of the relative strength of Bronsted acid sites present on the modified and unmodified catalysts suggested that PAs improved HDO when they provided new or stronger Bronsted acid sites. Additionally, the strength of the Bronsted acid sites provided by PA modifiers were tunable by altering the tail functionality, which affected the rates of HDO. These results suggest that PAs can be used to modify a variety of supports to prepare bifunctional acid-metal catalysts. (C) 2019 Elsevier Inc. All rights reserved.

In this study, convenient and selective oxidation of alcohols using aqueous hydrogen peroxide to yield carbonyl compounds was studied. Using the ruthenium-(4-methylphenyl-2,6-bispydinyl) pyridinedicarboxylate complex [Ru(mpbp)(pydic)] as a catalyst, primary and secondary alcohols were oxidized to aldehydes and ketones at room temperature with a satisfactory yield and excellent selectivity. The influence of various reaction parameters, such as solvent, catalyst and oxidant amount on both the activity and selectivity was also evaluated. Kinetic studies showed that the oxidation of alcohol was first order in terms of the substrate and hydrogen peroxide, and was second order in terms of the catalyst. A plausible mechanism involving ruthenium-oxo species with electrophilic character was proposed based on the in situ UV-vis spectroscopy studies and Hammett plots.

Herein, an efficient versatile nanocomposite constructed of melamine-functionalized graphene oxide nano-sheets (GO@melamine), iron oxide nanoparticles (Fe3O4 NPs), and zinc oxide (ZnO NPs) is presented. Moreover, two different applications have been studied for the prepared Fe3O4/GO@melamine-ZnO nanocomposite: First, as a heterogeneous catalyst for synthesis of pyrano[2,3-c]pyrazole derivatives in short reaction time (10 min) with high yields (96 %), second, as a substantial electrical supercapacitor with typical capacitive behavior, high resistance, and excellent electrode stability. From the catalytic aspect, high effectiveness, convenient isolation, and significant reusability could be referred as the distinguished properties for the produced nanocomposite. Turn-over number (TON) and turn-over frequency (TOF) values for the presented catalytic system have been estimated 17.2 x 10(6) and 1.71 x 10(6) min(-1), respectively, which revealed high catalytic performance of this catalytic system. From electrochemical aspect, economic benefits for fabrication of the introduced nanocomposite containing low-cost materials, make it as a suitable electrical supercapacitor for industrial applications.

The substitution of hydrogen atoms with fluorine in bioactive molecules can greatly impact physicochemical, pharmacokinetic, and pharmacodynamic properties. However, current synthetic methods cannot readily access many fluorinated motifs, which impedes utilization of these groups. Thus, the development of new methods to introduce fluorinated functional groups is critical for developing the next generation of biological probes and therapeutic agents. The synthesis of one such substructure, the alpha,alpha-difluoroalkylthioether, typically requires specialized conditions that necessitate early-stage installation. A late-stage and convergent approach to access alpha,alpha-difluoroalkylthioethers could involve nucleophilic addition of thiols across gem-difluorostyrenes. Unfortunately, under basic conditions, nucleophilic addition to gem-difluorostyrenes generates an anionic intermediate that can undergo facile elimination of fluoride to generate alpha-fluorovinylthioethers. To overcome this decomposition, we herein exploit an acid-based catalyst system to facilitate simultaneous nucleophilic addition and protonation of the unstable intermediate. Ultimately, the optimized mild conditions afford the desired alpha,alpha-difluoroalkylthioethers in high selectivity and moderate to excellent yields. These alpha,alpha-difluoroalkylthioethers are less nucleophilic and more oxidatively stable relative to nonfluorinated thioethers, suggesting the potential application of this unexplored functional group in biological probes and therapeutic agents.

This study describes the first use of a bis(phosphoranyl) methanido aluminum hydride, [ClC(PPh(2)NMes)(2)AlH2] (2, Mes = Me3C6H2), for the catalytic hydroboration of CO2. Complex 2 was synthesized by the reaction of a lithium carbenoid [Li(Cl)C(PPh(2)NMes)(2)] with 2 equiv of AlH3 center dot NEtMe2 in toluene at -78 degrees C. 2 (10 mol %) was able to catalyze the reduction of CO2 with HBpin in C6D6 at 110 degrees C for 2 days to afford a mixture of methoxyborane [MeOBpin] (3a; yield: 78%, TOF: 0.16 h(-1)) and bis(boryl)oxide [pinBOBpin] (3b). When more potent [BH3 center dot SMe2] was used instead of HBpin, the catalytic reaction was extremely pure, resulting in the formation of trimethyl borate [B(OMe)(3)] (3e) [catalytic loading: 1 mol % (10 mol %); reaction time: 60 min (5 min); yield: 97.6% (>99%); TOF: 292.8 h(-1) (356.4 h(-1))] and B2O3 (3f). Mechanistic studies show that the Al-H bond in complex 2 activated CO2 to form [ClC(PPh(2)NMes)(2)Al(H){OC(O)H}] (4), which was subsequently reacted with BH3 center dot SMe2 to form 3e and 3f, along with the regeneration of complex 2. Complex 2 also shows good catalytic activity toward the hydroboration of carbonyl, nitrile, and alkyne derivatives.

E-cigarettes have become very popular, a trend that has been stimulated by the wide variety of available e-liquid flavours. Considering the large number of e-liquid flavours (>7000), there is an urgent need to establish a screening strategy to prioritize the flavouring substances of highest concern for human health. In the present study, a prioritization strategy combining analytical screening, in silico tools and literature data was developed to identify potentially genotoxic e-liquid flavourings. Based on the analysis of 129 e-liquids collected on the Belgian market, 60 flavourings with positive in silico predictions for genotoxicity were identified. By using literature data, genotoxicity was excluded for 33 of them whereas for 5, i.e. estragole, safrole, 2-furylmethylketon, 2,5-dimethyl-4-hydroxyl-3(2H)-furanone and transhexanal, there was a clear concern for in vivo genotoxicity. A selection of 4 out of the remaining 22 flavourings was tested in two in vitro genotoxicity assays. Three out of the four tested flavourings induced gene mutations and chromosome damage in vitro, whereas equivocal results were obtained for the fourth compound. Thus, although there is a legislative framework which excludes the use of CMR compounds in e-liquids, flavourings of genotoxic concern are present and might pose a health risk for e-cigarette users.
