Herein, we report on the synthesis of alkyl-, aryl-, and alkynyl-substituted chlorotriazines and their ammonium salts, and demonstrate their utility in dehydrative condensation reactions. Although the electrophilicity of these reagents is mainly dependent on the hybridization of the carbon-substituents, it was found that bulky 2,6-dimethylphenyl group-substituted reagents resulted in the highest product yields because of a slight increase in reagent electrophilicity and/or steric hindrance favorable for desired dehydrative condensation reactions.

Artemisia fragrans is an aromatic and perennial herb with green silver leaves and yellow flowers, widely distributed in Iran, Azerbaijan, Russia and Turkey. The plant and its essential oil (EO) are used in traditional medicine and have economic value. In this study, the composition, antibacterial and antioxidant activities of 16 A. fragrans essential oil samples collected from different habitats in Iran were analyzed. A total of 85 compounds were detected using GC-MS analysis, the major constituents being camphor (9.91-34.44 %), alpha-thujone (19.22-42.63 %) and 1,8-cineole (12.57-31.87 %). Davanone D, alpha-cadinol, verbenene, ortho-oci-men were detected in the analysis as the new components for this species and are first reported by us. Anti-bacterial activity and minimum inhibitory and bactericidal concentrations of EOs were tested on Escherichia coli, Klebsiella pneumonia and Proteus vulgaris (Gram-negative strains) Staphylococcus aureus, Staphylococ-cus epidermidis and Bacillus subtilis (Gram-positive strains). The EOs showed better inhibitory effects against Gram-negative strains compared to Gram-positive ones. Among the EOs, E7 (IC50 = 9.1 mu g/mL) population showed the highest radical scavenging capacity, which was equal to the positive control (butylated hyroxytoluene). The quantitative and qualitative variability of the studied EOs and their antibacterial and antioxidant activities may be recommended for pharmacological and cosmetic industries.

A Ni salt of phosphomolybdic acid (NiHPMA) was synthesized and characterized by various physico-chemical techniques such as EDX, UV-Visible spectroscopy, FT-IR, Raman spectroscopy and XPS. FT-IR and Raman spectroscopy confirm the presence of Ni as a counter cation while UV-Visible and XPS studies to confirm the presence of Ni(ii) in the catalyst. The catalyst was evaluated for its bi-functional activity towards the tandem conversion of benzaldehyde to ethyl benzoate and it was found that very small amounts of Ni (2.64 x 10(-3)mmol) enhance the selectivity towards benzoate. A detailed mechanistic study was carried out by UV-Visible and Raman spectroscopy to confirm that both intermediate species, Mo-peroxo and Ni-oxo, are responsible for higher selectivity towards esters. Further, a study to determine the effect of addenda atoms (heteropoly acid) was also carried out. The catalyst was also found to be viable for a number of aldehydes under optimized conditions.

A pyridine-based amide functionalized tetracarboxylic acid, 5,5 ‘-(pyridine-2, 6-dicarbonyl)bis(azanediyl)}diisophthalic acid (H4L), was synthesized and its coordination chemistry toward zinc(II) and cadmium(II) ions was studied. The reactions of H4L with Zn(NO3)(2).6H(2)O and Cd(NO3)(2).4H(2)O led to its full or partial deprotonation, respectively, and the formation of the 2D coordination polymers [Zn-2(L)(H2O)(4)](n).4n(H2O) (1) and [Cd-3(HL)(2)(DMF)(4)](n).4n(DMF) (2) (DMF = N,N’-dimethylformamide), respectively. They were characterized by elemental analysis, FT-IR, photoluminescence, thermogravimetry, and single-crystal and powder X-ray diffraction. In 1, the L4- ligand is planar with every carboxylate anion binding a Zn(II) cation and giving rise to a 2D grid with the metals with tetrahedral environments. In 2, the combination of bridging HL3- and dimethylformamide to form trinuclear Cd(II) clusters engenders secondary building block units and generates a layer-type 2D network with the metals with octahedral and pentagonal bipyramid coordination geometries. The topological analyses of 1 and 2 reveal 2,4-connected and 3,6-connected binodal nets, respectively. On account of the presence of Lewis acid (Zn or Cd centers) as well as basic (uncoordinated pyridine and amide groups) sites, 1 and (to a much lower extent) 2 effectively catalyze the one-pot cascade deacetalization-Knoevenagel condensation reactions under quite mild conditions. They act as heterogeneous catalysts, being easy to recover and recycle without losing activity.

Catalytic conversion of lignin to versatile aromatic compounds is attracting increasing attention. However, it is highly desirable but challenging to produce a specific chemical with high yield through lignin depolymerization in a one-pot process because of the complex structure of the lignin molecule (mainly composed of H, G, and S units). In this study, a series of metal-based deep eutectic solvents (M-DESs) were prepared and used for the catalytic tailoring of lignin H units to produce value-added methyl p-hydroxycinnamate (MPC). In particular, M-DES ChCl[FeCl3](2) showed excellent catalytic performance for the selective production of MPC as the sole product with high yield and selectivity (105.8 mg g(-1) and 74.1%, respectively). Extensive characterizations using 2D HSQC NMR, C-13 NMR, and GPC demonstrated that MPC was obtained from the selective tailoring of p-coumaric acid (pCA) units via the cleavage of ester bonds in lignin. Furthermore, M-DES ChCl[FeCl3](2) also exhibited efficiency to other herbaceous lignins, and showed excellent recyclability. Therefore, this work provides an effective strategy for the valorization of lignin.

Bark is the traditional medicinal component of Eucommia ulmoides Oliver (E. ulmoides). However, the demand for E. ulmoides medicinal materials seriously limits their sustainability. To alleviate resource constraints, the bioactivity of E. ulmoides leaves and its pharmacodynamic basis were investigated. In the present study, extracts of E. ulmoides leaves were found to display potential renal protective properties in rat glomerular mesangial (HBZY-1) cells treated with high levels of glucose, suggesting that they possess potential factors capable of treating diabetic nephropathy. Ultra-performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was used to comprehensively characterize the chemical components of E. ulmoides leaves. A total of 83 possible chemical components, including 12 iridoids, 13 flavonoids, 14 lignans, 20 phenylpropanoids, 14 phenolic acids, and 10 additional components, were identified in E. ulmoides leaves. Network pharmacology was used for a preliminary exploration of the potential mechanism of action of renal protection afforded by E. ulmoides leaves towards diabetic nephropathy. The network pharmacology results were verified using a series of biological experiments. The present study provided the basis for the comprehensive development and utilization of E. ulmoides leaves and the discovery of potential drugs.

Unactivated alkyl chlorides are abundant building blocks in organic synthesis, but they have been rarely engaged in cross-electrophile coupling. Herein, we report a Ni/Ti-cocatalyzed reductive allylic defluorinative cross -coupling between trifluoromethyl alkenes and unactivated alkyl chlorides and bromides, enabling the efficient preparation of diverse functional-group-rich gem-difluoroalkenes. Notably, synthesis of the gem-difluoroalkene analogues of azaperone, haloperidol, and benperidol was also accomplished using our method as a key step.

Abundant aromatic carboxylic acids exist in great structural diversity from nature and synthesis. To date, the synthetically valuable decarboxylative functionalization of benzoic acids is realized mainly by transition-metal-catalyzed decarboxylative cross couplings. However, the high activation barrier for thermal decarboxylative carbometalation that often requires 140 degrees C reaction temperature limits both the substrate scope as well as the scope of suitable reactions that can sustain such conditions. Numerous reactions, for example, decarboxylative fluorination that is well developed for aliphatic carboxylic acids, are out of reach for the aromatic counterparts with current reaction chemistry. Here, we report a conceptually different approach through a low-barrier photoinduced ligand to metal charge transfer (LMCT)-enabled radical decarboxylative carbometalation strategy, which generates a putative high-valent arylcopper(III) complex, from which versatile facile reductive eliminations can occur. We demonstrate the suitability of our new approach to address previously unrealized general decarboxylative fluorination of benzoic acids.

Synthetic insecticides, a traditional tool to avoid the reduction of stored-product due to insects, have emerged a serious of hazards to the environment for years, therefore, botanicals have entered people’s vision. This work aimed to present the essential oil composition of Melaleuca bracteata, and the contact as well as repellent activities against three stored-product insects, i.e. Lasioderma serricorne (Coleoptera: Ptinidae), Tribolium castaneum (Coleoptera: Tenebrionidae), and Sitophilus oryzae (Coleoptera: Curculionidae). For determining the composition, the analysis was performed by GC/FID and GC/MS. Among 11 identified compounds, the principal compounds were methyl eugenol (88.52 %) and methyl cinnamate (7.90 %). The essential oil demonstrated contact toxicity against L. serricorne, T. castaneum, and S. oryzae which LD50 values were 3.2, 22.6, and 20.4 mu g/adult, respectively. Methyl cinnamate was more effective than methyl eugenol. The repellent activity indicated that essential oil and major compositions of M. bracteata were effective against L. serricorne and T. castaneum, but no use for S. oryzae. In the contact assay, L. serricorne showed more sensitivity, however, in repellency assay, T. castaneum was susceptible. We seek to provide a new application of the popular ornamental plant, M. bracteata, and offer an alternative material to botanical insecticides development.
