The borane-catalyzed synthesis of dihydroquinoline-4-ones is developed. The amino-substituted chalcones undergo a 1,7-hydride shift upon Lewis acid activation to form a zwitterionic iminium enolate, which collapses to the dihydroquinoline-4-one scaffold. The reaction proceeds in high yields (75-99%) with an excellent diastereoselectivity of up to >99:1 (cis:trans). The reaction mechanism is investigated by kinetic, isotope labeling, and computational experiments.

Volatile content during postharvest is a critical factor affecting the quality of rose products. However, changes in the volatile content of cut rose flowers during vase life have not yet been identified although the maturity of flower petals may result in the significant changes of volatile profiles. The present study investigated volatile changes in the petals of two rose varieties, ‘Fuego’ exhibited to longer vase life and ‘Red eagle, during vase life. ‘Fuego’ petals contained 31 volatiles, of which 12 increased and 11 decreased in content during vase life. ‘Red Eagle’ petals contained 37 volatiles, of which 9 increased and 19 decreased. The major components that increased during vase life included 2-ethylhexan-1-ol and phenylmethanol in ‘Fuego’ and hexan-1-ol and 2-phenylacetaldehyde in both cultivars, whereas the major components that decreased during vase life included methyl butanoate in ‘Fuego’, 3,5-dimethoxytoluene in ‘Red Eagle’, and 2-methylhexane in both cultivars. The total volatile content was maintained in ‘Fuego’ petals during the 6-day vase life, despite the changes in the content of individual volatile compound. By contrast, the total volatile content of ‘Red Eagle’ petals significantly decreased during vase life. Additionally, the volatile compounds that increased in content were relatively small molecules (<= C-8), whereas those that decreased in content during vase life were relatively large molecules (>= C-9). These results suggest that the analysis of volatile changes during vase life contribute to the harvest time selection of rose flowers and the determination of petal stages used for essential oil in many rose varieties.

Owing to the increasing amount of waste materials around the globe, the conversion of waste or secondary by-products to value-added products for various applications has gained significant interest. Herein, two novel agro-food waste products, Musa sp. ‘Malbhog’ peel ash (MMPA) and Musa Champa Hort. ex Hook. F. peel ash (MCPA) are used as catalysts to promote an inexpensive, efficient and eco-friendly carbon-carbon bond forming crossed aldol reaction at room temperature in solvent free conditions. Furthermore, the resulting products were subjected to reactions with these promoters in an oxygen atmosphere and led to the formation of novel flavone derivatives. Moreover, the used catalysts were properly characterized using different sophisticated analytical techniques such as Fourier-transform infrared spectroscopy (FT-IR), X-ray diffractometry (XRD), Brunauer-Emmett-Teller analysis (BET), Raman spectroscopy, scanning electron microscopy energy dispersive X-ray spectroscopy (SEM-EDS), transition electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA) along with element detection using atomic absorption spectroscopy and ion chromatographic methods. These two approaches are metal free, as well as being devoid of any extra additives, co-catalysts, harsh conditions, the use of column chromatography for purification and result in a higher yield of the product within a short space of time. The catalytic abilities of the promoter were also examined to synthesize important bioactive molecules such as butein and apigenin at room temperature. With gram scale synthesis of the chalcone derivatives, the used catalysts (MMPA and MCPA) were further reused for five cycles and did not demonstrate any loss in catalytic activity.

A full understanding of changes of the microbiome and metabolome during Napier grass silage in relation to aerobic exposure can improve the nutritional value and extend the aerobic stability of this important feed in tropical and subtropical regions. The round bale silage of Napier grass was prepared with deionized water (control) and screened strains Lactobacillus rhamnosus LR753 (LR753) and L. buchneri 40788 (LB). Silages were stored at ambient temperature (30-40 degrees C) for 60 days, followed by 2 and 4 days of aerobic exposure. Strains LB and LR753 significantly improved aerobic stability (>84 h vs. 18 h of control) of baled Napier grass silage by inhibiting the growth of Saccharomycetales as for the higher production of acetic acid (P < 0.05). Weissella and Issatchenkia spp. were the dominant bacteria and fungi in 60-day silage, respectively. LC-MS/MS detected a total of 426 metabolites throughout ensiling and aerobic exposure. With the decrease of Weissella spp. and the increase of Acetobacter spp., the metabolites associated with both were mainly odor-related (3-methylbutanoic acid, isoquinoline, and cuminaldehyde) and amines (tryptamine and tyramine) in control silage, while more antimicrobial activity metabolites were found in strains LB and LR753-treated silage (methylbutanoic acid, 1,2-propanediol, and tiglic acid). Screened local strain LR753 showed a promising potential for improving silage fermentation and aerobic stability of Napier grass. The present study indicates that adequately describing the microbiome and metabolome of silages during fermentation and aerobic exposure can improve ensiling practices and the screening of silage inoculants that act synergistically with the natural microbiome of the forage in hot and humid areas.

A one-pot and modular approach to the synthesis of 2,4(5)-disubstituted imidazoles was developed based on ketone oxidation, employing catalytic HBr and DMSO, followed by imidazole condensation with aldehydes. This methodology afforded twenty-nine disubstituted NH-imidazoles (23%-85% yield). A three-step synthesis of 20 kinase inhibitors was achieved by employing this oxidation- condensation protocol, followed by bromination and Suzuki coupling in the imidazole ring to yield trisubstituted NH-imidazoles (23%-69%, three steps). This approach was also employed in the synthesis of known inhibitor GSK3037619A.

In spite of the enormous promise that polymeric carbon nitride (PCN) materials hold for various applications, the fabrication of high-quality, binder-free PCN films and electrodes has been a largely elusive goal to date. Here, we tackle this challenge by devising, for the first time, a water-based sol-gel approach that enables facile preparation of thin films based on poly(heptazine imide) (PHI), a polymer belonging to the PCN family. The sol-gel process capitalizes on the use of a water-soluble PHI precursor that allows formation of a non-covalent hydrogel. The hydrogel can be deposited on conductive substrates, resulting in formation of mechanically stable polymeric thin layers. The resulting photoanodes exhibit unprecedented photoelectrochemical (PEC) performance in alcohol reforming and highly selective (similar to 100 %) conversions with very high photocurrents (>0.25 mA cm(-2) under 2 sun) down to <0 V vs. RHE. This enables even effective PEC operation under zero-bias conditions and represents the very first example of a 'soft matter'-based PEC system capable of bias-free photoreforming. The robust binder-free films derived from sol-gel processing of water-soluble PCN thus constitute a new paradigm for high-performance 'soft matter' photoelectrocatalytic systems and pave the way for further applications in which high-quality PCN films are required.

Metabolites can distinguish pathogenic from healthy cells, but they are hard to couple to current photosensitizers without altering their biological activity. Here the authors design a new family of photosensitizers that retain metabolite function to target pathogenic cells and ablate them by photodynamic therapy. Photoactivatable molecules enable ablation of malignant cells under the control of light, yet current agents can be ineffective at early stages of disease when target cells are similar to healthy surrounding tissues. In this work, we describe a chemical platform based on amino-substituted benzoselenadiazoles to build photoactivatable probes that mimic native metabolites as indicators of disease onset and progression. Through a series of synthetic derivatives, we have identified the key chemical groups in the benzoselenadiazole scaffold responsible for its photodynamic activity, and subsequently designed photosensitive metabolic warheads to target cells associated with various diseases, including bacterial infections and cancer. We demonstrate that versatile benzoselenadiazole metabolites can selectively kill pathogenic cells – but not healthy cells – with high precision after exposure to non-toxic visible light, reducing any potential side effects in vivo. This chemical platform provides powerful tools to exploit cellular metabolic signatures for safer therapeutic and surgical approaches.

A cross-selective aza-pinacol coupling of aldehydes and imines has been developed to afford valuable beta-amino alcohols. This strategy enables chemoselective conversion of aliphatic aldehydes to ketyl radicals, in the presence of more easily reduced imines and other functional groups. Upon carbonyl-specific activation by AcI, a photoinitiated Mn catalyst selectively reduces the resulting alpha-oxy iodide by an atom transfer mechanism. The ensuing ketyl radical selectively couples to imines, precluding homodimerization by a classical reductive approach. In this first example of reductive, ketyl coupling by atom transfer catalysis, Zn serves as a terminal reductant to facilitate Mn catalyst turnover. This new strategy also enables ketyl radical couplings to alkenes, alkynes, aldehydes, propellanes, and chiral imines.

The non-linear optical technology is gaining huge attention to the thermal and mechanical stability, electrical property, and modulate signal flexibility that could be used in uprising optoelectronics devices based on powerful laser technologies such as all optical switches, lightemitting diodes, data storage and optical communication systems. In this paper, selected three phenanthrolines derivatives [2-phenyl-1H-phenanthro[9,10-d]imidazole (1), 2-(4-nitrophenyl)1H-phenanthro[9,10-d]imidazole(2),2-(4-methoxyphenyl)-1H phenanthro[9,10-d]imidazole (3)] were synthesized and characterized using UV, FT-IR and H-1 NMR. Cubic nonlinear optical properties susceptibility (chi(<3>)(THG)) were analyzed and evaluated using the third harmonic generation technique on thin films at 1064 nm. The investigation study is completed by a theoretical calculation in which the different quantum chemical parameters like frontier molecular orbital analysis, energy gap, dipole moment, average polarizability, and first second hyperpolarizability were analyzed using Density Functional Theory (DFT). The non-linear optical behavior of the selected three phenanthrolines derivatives is confirmed through the obtained high THG efficiency. Moreover, a significant correlation between the molecular structures and the optoelectronic properties is demonstrated.
