Ren, Zili published the artcileConstruction of oxime ester derivatives of osthole from Cnidium monnieri, and evaluation of their agricultural activities and control efficiency, SDS of cas: 104-03-0, the publication is Pest Management Science (2020), 76(11), 3560-3567, database is CAplus and MEDLINE.

In order to discover natural-product-based pesticidal candidates, a series of coumarin-like derivatives containing oxime ester fragments at the C-8 position were prepared by structural modification of osthole, a natural plant product isolated from Cnidium monnieri. Their pesticidal activities were evaluated against two typically fruit trees/crop-threatening agricultural pests, Mythimna separata Walker and Tetranychus cinnabarinus Boisduval. Osthole was regioselectively oxidized by selenium dioxide to give the E-isomer, (2¡äE)-3¡ä-formaldehydylosthole (2). Four key steric structures of 2, (2¡äE, 4¡äE)-(o-chloropyrid-3-ylcarbonyl)oximinylosthole (4o), (2¡äE, 4¡äE)-(styrylcarbonyl)oximinylosthole (4t), and (2¡äE, 4¡äE)-(acetyl)oximinylosthole (4w) were undoubtedly confirmed by X-ray crystallog. Against T. cinnabarinus, it is noteworthy that (2¡äE, 4¡äE)-(p-chlorophenylcarbonyl)oximinylosthole (4c) exhibited over three-fold more potent acaricidal activity of the precursor osthole, with especially good control efficiency observed in the glasshouse. Against M. separata, compounds 4c and (2¡äE, 4¡äE)-(p-nitrophenylcarbonyl)oximinylosthole (4f) showed the most pronounced growth inhibitory activity. The relationships between their structures and agricultural activities also were studied. These results demonstrate that compound 4c could be further structurally modified as pesticidal agents. It will lay the foundation for future application of osthole derivatives as pesticides.

Pitchumani, Venkatachalam published the artcileStudies on Thiourea Catalysed Bromocycloetherification and Bromolactonisations*, Formula: C10H10O3, the publication is Australian Journal of Chemistry (2020), 73(12), 1292-1295, database is CAplus.

Lewis base catalyzed halofunctionalisation reactions of alkenes are well established and allow access to, among others, various oxygen containing heterocycles. By exploiting the known conversion of N-heterocyclic carbenes into the corresponding thioureas it has been possible to prepare and study a range of chiral and non-chiral Lewis base catalysts for such reactions. Although all thiourea catalysts were found to mediate bromocycloetherification and bromolactonisation reactions, they could not be achieved with enantioselectivity.

Zhao, Haoqiang published the artcileLigand-Promoted Rh^I-Catalyzed C2-Selective C-H Alkenylation and Polyenylation of Imidazoles with Alkenyl Carboxylic Acids, Product Details of C9H7NO4, the publication is Chemistry – A European Journal (2022), 28(36), e202200441, database is CAplus and MEDLINE.

The first RhI-catalyzed, directed decarbonylative C2-H alkenylation of imidazoles with readily available alkenyl carboxylic acids is reported. The reaction proceeds in a highly regio- and stereoselective manner, providing efficient access to C2-alkenylated imidazoles that are generally inaccessible by known C-H alkenylation methods. This transformation accommodates a wide range of alkenyl carboxylic acids, including challenging conjugated polyene carboxylic acids, and diversely decorated imidazoles with high functional group compatibility. The presence of a removable pyrimidine directing group and the use of a bidentate phosphine ligand are pivotal to the success of the catalytic reaction. This process is also suitable for benzimidazoles. Importantly, the scalability and diversification of the products highlight the potential of this protocol in practical applications. Detailed exptl. and computational studies provide important insights into the underlying reaction mechanism.

Cobalt-catalyzed selective transformation of levulinic acid and primary amines into pyrrolidines and pyrrolidinones under H₂ was developed. The catalyst system consisting of Co(NTf₂)₂, 1,1,1-tris(di(4-methoxyphenyl)phosphinomethyl) ethane ((p-anisyl)triphos) and Me₃SiOTf works well for the synthesis of pyrrolidines via reductive amination/cyclization/deoxygenative reduction of amide, and using Co(NTf₂)₂/1,1,1-tris(diphenylphosphinomethyl) ethane (triphos) as the catalyst under reduced hydrogen pressure results in exclusive formation of pyrrolidinones. Both aryl and alkyl primary amines are suitable substrates, and a variety of functional groups are tolerated. Meanwhile, 4-oxo-4-arylbutanoic acids, 5-oxohexanoic acid, 6-oxoheptanoic acid, 2-formylbenzoic acid, 2-acetylbenzoic acid and 2¡ä-acetyl-[1,1¡ä-biphenyl]-2-carboxylic acid are also applicable, allowing for convenient access to cyclic amines and lactams with different ring size.

Liu, Xiangxiang published the artcileFunctional Porous Organic Polymers Comprising a Triaminotriphenylazobenzene Subunit as a Platform for Copper-Catalyzed Aerobic C-H Oxidation, Computed Properties of 457-68-1, the publication is Chemistry of Materials (2019), 31(15), 5421-5430, database is CAplus.

Developing functional porous materials as a platform for the heterogeneous catalytic oxidation reaction provides a good way to solve the high environmental issues resulted by traditional oxidation processes in the industry. This article reported a design and facile synthesis of N-rich functional porous organic polymers with mesopores such as Azo-POP-4, Azo-POP-5, and Azo-POP-6 based on the triaminotriphenylazobenzene subunit for the first time. The nitrogen-rich POPs with the triaminotriphenylazobenzene subunit was found to remove 85% of copper ions from water within 30 min. The as-synthesized Cu@Azo-POP-4 demonstrated high catalytic reactivity and selectivity in aerobic C-H bond oxidation to afford the desired ketones in high yield. In addition, the catalyst could be reused easily five times without decreasing the reactivity, which will help to design catalysts reducing environmental pollution and advance the chem. technol.

Li, Jianqiao published the artcileThe effect of multiple pairs of meta-dicarboxyl groups on molecular self-assembly and the selective adsorption of coronene by hydrogen bonding and van der Waals forces, Related Products of catalysis-chemistry, the publication is Nano Research (2022), 15(2), 1691-1697, database is CAplus.

The prediction of two-dimensional mol. self-assembly structures has always been a problem to be solved. The mols. with meta-dicarboxyl groups can self-assemble into a specific hexagonal cavity, which has an important influence on the prediction of mol. self-assembly structures and the application of functional mols. with meta-dicarboxyl groups. Two kinds of mols. with four pairs of meta-dicarboxyl groups, 1,3,6,8-tetrakis(3,5-isophthalic acid)pyrene (H8TIAPy) and 4¡ä,4¡ä¡ä¡ä,4¡ä¡ä¡ä¡ä¡ä,4¡ä¡ä¡ä¡ä¡ä¡ä¡ä-(ethene-1,1,2,2-tetrayl)tetrakis(([1,1¡ä-biphenyl]-3,5-dicarboxylic acid)) (H8ETTB) mols. were chosen to observe the self-assembly behavior at the heptanoic acid/highly oriented pyrolytic graphite (HA/HOPG) interface. H8TIAPy mols. self-assembled into well-ordered quadrilateral structures and could be regulated into kagome networks with hexagonal pores by coronene (COR) mols. H8ETTB mols. self-assembled into lamellar structures and transformed into acid-COR-acid-COR co-assembled structures at low concentration of COR solution and acid-COR dimer-acid-COR dimer co-assembled structures at high concentration of COR solution The reason that H8ETTB mols. could not be regulated into hexagonal porous architecture was attributed to the steric hindrance by the similar length and width of H8ETTB mols. The H8ETTB templates had stronger adsorption for COR than that of hexaphenylbenzene (HPB), regardless of the order of mol. introduction.
