Electronic cigarettes (e-cigarettes) have become popular alternatives to traditional tobacco. Despite this, a comprehensive evaluation of their long-term effects and safety for the consumers and the environment is missing. To contribute to filling this gap, headspace solid-phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME/GC-MS) was employed to establish and compare the volatile fingerprints of traditional tobacco and e-cigarettes. The analysis of traditional tobacco included two popular brands and different parts of the cigarette (solid tobacco, cigarette smoke, cigarette paper and filter). Regarding the e-cigarettes, two e-liquids, with and without nicotine, their main constituents (e-bases) and corresponding vapours, obtained under default vaping (power) conditions, were analysed. A total of 80 volatile organic compounds (VOCs) were identified in traditional tobacco, of which 14 carbonyl compounds, 9 benzene derivatives, 9 ethyl esters and 9 hydrocarbons. Slight differences in the volatile profile of cigarette paper and filter between the two brands were also detected, showing that exogenous components of tobacco influence the flavour and harmfulness perceived by the smokers. In turn, 92 VOCs were identified in e-cigarettes, including 31 ethyl esters, 18 alcohols and 10 hydrocarbons. No VOCs with potentially toxic or harmful effects were identified in the vapour of Do It Yourself (DIY) liquids and Premium samples. Therefore, taking into consideration the volatile compositions obtained for smoking and vaping procedures under normal conditions of operation and using certified e-liquid mixtures, the e-cigarettes analysed seemed to constitute a valid and less harmful alternative to traditional tobacco for smokers, secondhand smokers and the environment.

A nanomagnetic catalyst based on the nano-Fe3O4 core was synthesized and used in the synthesis of the hexahydroquinoline derivatives which acts as a solid heterogeneous catalyst. The as-prepared catalyst was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction, energy dispersive X-ray spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, vibrational sample magnetometry, and thermal gravimetric analysis. Catalyst activity was tested in the synthesis of hexahydroquinoline derivatives. The FTIR shows that the catalyst can activate as the carbonyl group of the benzaldehyde, so that it can motivate the reaction. The proposed method has important features which include solvent free, mild, high yield, shorter reaction time, easy preparation and separation of the catalyst, and efficient workup procedure. On the other hand, the design of experiment was used as a systematic method for the programing of the reaction condition. Optimization showed that the optimal reaction temperature and amount of catalyst were 65 degrees C and 0.05 g, respectively.

We discovered that metal center confined in the porphyrin structure can process lower valence state (LV) via reversible photoinduced electron transfer in both singlet and triplet states, which are confirmed by X-ray photoelectron spectroscopy (XPS), X-ray absorption fine structure (XAFS), electron spin resonance (ESR) and density functional theory (DFT) calculations. More importantly, this controlling strategy was hardly influenced by the electronegative properties of surrounding porphyrin structures, at the same time, it can be widely applied to various metal elements such as Zn, Cu, Ni, Co, Fe. This work provides a new vision to fabricate and deeply understand the metal center with lower valence state from single atom level.

Natural product (NP) structures are a rich source of inspiration for the discovery of new biologically relevant chemical matter. In natural product inspired pseudo-NPs, NP-derived fragments are combined de novo in unprecedented arrangements. Described here is the design and synthesis of a 155-member pyrroquinoline pseudo-NP collection in which fragments characteristic of the tetrahydroquinoline and pyrrolidine NP classes are combined with eight different connectivities and regioisomeric arrangements. Cheminformatic analysis and biological evaluation of the compound collection by means of phenotyping in the morphological cell painting assay followed by principal component analysis revealed that the pseudo-NP classes are chemically diverse and that bioactivity patterns differ markedly, and are dependent on connectivity and regioisomeric arrangement of the fragments.

The Strecker reaction is a three-component condensation of an aldehyde, an amine, and hydrogen cyanide, delivering an a-amino carbonitrile. Despite extensive investigations, the possibility to use amides instead of amines as one of the three condensation partners has been largely neglected. Nonetheless, the N-acylated alpha-aminocarbonitriles that are obtained in this way are of direct interest for drug discovery, because they make up a well-known class of mechanism-based inhibitors of serine- and cysteine-type hydrolases. In response, we have thoroughly explored the corresponding variant of the Strecker reaction, focusing on catalyst use, solvent, reaction time, and cyanide source. Optimized parameters were combined in a sequential one-pot protocol for which the scope was found to be compatible with library synthesis applications. Product yields ranged from 7 to 90%, and conditions were found to be mild and tolerant to a wide range of functional groups, including moieties that are typically present in druglike molecules.

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.

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.
