A ruthenium-catalyzed photoredox coupling of substituted N-aryltetrahydroisoquinolines (THIQs) and different bench-stable pyridinium salts was successfully developed to give fast access to 1-benzyl-THIQs. Furthermore, secondary alkyl and allyl groups were also successfully introduced via the same method. Additionally, the typically applied N-phenyl group in the THIQ substrate could be replaced by the cleavable p-methoxyphenyl (PMP) group and successful N-deprotection was demonstrated.

I found the field of Engineering very interesting. Saw the article Magnetite nanoparticles functionalized with propolis against methicillin resistant strains of Staphylococcus aureus published in 2019.0. COA of Formula: C15H12O, Reprint Addresses Miguel, MG (corresponding author), Univ Algarve, Fac Sci & Technol, Dept Chem & Pharm, MeditBio, Campus Gambelas, P-8005139 Faro, Portugal..

Magnetite nanoparticles (MNPs) have been evaluated for inhibiting microbial growth and biofilm formation. In this study the effect of the nanocomposite Moroccan propolis extract / MNPs acting against methicillin resistant strains of Staphylococcus aureus (MRSA) was evaluated. Chemical composition of propolis was established by pyrolysis coupled to gas chromatography and mass spectrometry method (pyrolysis GC/MS). MNPs were obtained through the co-precipitation method. The fabricated nanostructure was characterized by X-ray Diffraction (DRX), Transmission Electron Microscopy (TEM), and Fourier Transform-Infrared Spectroscopy (FTIR). TEM of MNPs provided a particle average size of 15 nm, FTIR spectral analysis enabled a fast way of identification of MNPs, attesting the occurrence of the different combinations. The use of MNPs loaded with propolis and the antibiotic chloramphenicol at Minimum Inhibitory Concentration (MIC) value inhibited the bacterial growth of MSSA (methicillin susceptible strain of S. aureus) and MRSA strains. After the treatment with MNPs-OA-P-CLo nanocomposite (MNPs with oleic acid, propolis and chloramphenicol), the disruption of the bacterial cell was observed by TEM. The combination of propolis and chloramphenicol in free form at MIC value largely impaired both MSSA and MRSA strains as, after 2 h of treatment, no viable cells of MRSA 2 and MRSA 16 were recovered. Hence, the results elucidated a new antibacterial nanocomposite synthesis, for possible applications as prospective nanoantibacterial agents or drug carriers.

The Name is 1,1,1-Triethoxyethane. Through research, I have a further understanding and discovery of 78-39-7.

A novel strategy for the synthesis of delta-thiolactones from inexpensive and readily available gamma-unsaturated esters has been developed. This strategy incorporates a radical acyl thiol-ene reaction as the key C-S bond forming step. Cyclization is achieved via a Steglich-type thiolactonization of 5-mercaptopentanoic acids. We report the facile and scalable synthesis of delta-thiolactones in moderate to good yield under mild reaction conditions with tolerance for a range of functional groups.

The CAS is 78-39-7. Through research, I have a further understanding and discovery of 1,1,1-Triethoxyethane

A highly efficient and modular synthesis of nematode pheromone ascarosides was developed, which highlights a 4-step scalable synthesis of the common intermediate 10 in 23% yield from commercially available l-rhamnose by using orthoesterification/benzylation/orthoester rearrangement as the key step. Six diverse ascarosides were synthesized accordingly. Notably, biological investigations revealed that ascr#1 and ascr#18 treatment resulted in enhanced callose accumulation in Arabidopsis leaves. And ascr#18 also increased the expression of defense-related genes such as PR1, PDF1.2, LOX2 and AOS, which might contribute to the enhanced plant defense responses. This study not only allows a facile access to 1-O, 2-O, and 4-O substituted ascarosides, but also provides valuable insights into their biological activities in inducing plant defense response, as well as their mode of action.

A series of bis(tridentate) cyclometalated oligopyridine complexes [Fe-II(C<^> N<^>N)(L)](+) have been synthesized via the reactions of [Fe-II(C<^> N<^>N-py)Br(PMe3)(2)] (1, HC<^>N-py<^>N-py = 6-(phenyI)-2,2′-bipyridine) and [Fe-II(C<^>N-ppy<^>N-isoquin)Br(PMe3)(2)] (2, HC<^>N-ppy<^>N-isoquin = 3-(4,6-diphenylpyridin-2-yl)isoquinoline with tridentate ligands L, affording [Fe-II(C<^>N-ppy<^>N-py)(4′-R-tpy)](+) (3a-e, R = H, Cl, p-ClC6H4, p-MeOC6H4, p-tol, respectively; tpy 2,2′:6′,2 ”-terpyridine), [Fe-II(C<^>N-ppy<^>N-isoquin)(tpy)](+) (4), [Fe-II(C<^>N-ppy<^>N-py)(6-(Ph2PCH2)-bpy)](+) (5, bpy = 2,2′-bipyridine), and [Fe-II(C<^>N-py<^>N-py)(6-NHC-bpy)](+) (6, NHC = N-heterocyclic carbene). Complexes 3-6 exhibit bathochromically shifted absorption bands, markedly cathodically shifted E-1/2 (Fe-III/Fe-II) values, and narrowed electrochemical band gaps in comparison to those of [Fe-II(tpy)(2)](2+), as revealed by UV-vis absorption spectroscopy and cyclic voltammetry. DFT and TDDFT calculation studies revealed strong mixing of MLCT with LLCT transitions as origins to the major absorption bands. Complex 6 incorporating a cyclometalating unit and an NHC donor exhibits panchromic absorption, and 5 shows markedly enhanced molar absorptivity in the visible region. A femtosecond transient absorption spectroscopic study of 6, coupled with DFT and TDDFT calculations and spectroelectrochemical measurements, gave evidence for the possible involvement of a (MLCT)-M-3 state with a lifetime of 21.4 ps.

We herein report highly chemoselective transfer hydrogenation of alpha,beta-unsaturated carbonyl compounds to saturated carbonyls with formic acid as a hydrogen donor over a stable and recyclable heterogeneous Pd nano particles (NPs) on N,O-dual doped hierarchical porous biomass-derived carbon. The synergistic effect between Pd NPs and incorporated heteroatoms on carbon plays a critical role on promoting the reaction efficiency. A series of alpha,beta-aromatic and aliphatic unsaturated carbonyl compounds was selectively reduced to their corresponding saturated carbonyls in up to 97% isolated yields with good tolerance of various functional groups. In addition, the catalyst can be successively reused for at least 6 times without significant loss in reaction efficiency.

The synthesis of phytol-derived gamma -butyrolactones as well as their evaluation for deterrent activity towards peach-potato aphid Myzus persicae and antiproliferative activity against four selected cancer cell lines are reported. Products were obtained in good yields (19-96%) and their structures were fully characterized by spectroscopic data (NMR, HRMS). Four synthesized delta -halo-gamma -lactones (4-7) are new and have not been previously described in the literature. In the choice test phytol (1) appeared deterrent to M. persicae, whereas modifications of its structure did not cause the avoidance of the treated leaves by the aphids. In contrast, aphids were attracted to the leaves treated with the new trans-delta -chloro-gamma -lactone (6). Electrical Penetration Graph (EPG) technique applied to explore the aphid probing and feeding activity revealed that neither phytol nor lactone 6 affected aphid probing and the consumption of phloem sap, which means that both phytol and the lactone 6 might have acted as postingestive modifiers of aphid behavior. The results of in vitro antitumor assays showed that obtained phytol derivatives exhibit cytotoxic activity against studied cancer cell lines (leukemia, lung and colon carcinoma and its doxorubicin resistant subline). Halolactones 4-6 were identified as the compounds, which arrest cell cycle of leukemia cells mainly in G2/M and S phases.

Ketones are of great importance in synthesis, biology, and pharmaceuticals. This paper reports an iridium complexes-catalyzed cross-coupling of alcohols via hydrogen borrowing, affording a series of alpha-alkylated ketones in high yield (86 %-95 %) and chemoselectivities (>99 : 1). This methodology has the advantages of low catalyst loading (0.1 mol%) and environmentally benign water as the solvent. Studies have shown the amount of base has a great impact on chemoselectivities. Meanwhile, deuteration experiments show water plays an important role in accelerating the reduction of the unsaturated ketones intermediates. Remarkably, a gram-scale experiment demonstrates this methodology of iridium-catalyzed cross-coupling of alcohols has potential application in the practical synthesis of alpha-alkylated ketones.
