Han, Guibiao published the artcileThe sex pheromone communication system of adult jujube leafroller Ancylis sativa Liu, Product Details of C14H26O2, the publication is Kunchong Xuebao (1999), 42(1), 5-30, database is CAplus.

The titer and precise ratio of multi-components of A. sativa sex pheromone were determined by using anal. technique of single sex pheromone gland. The results showed that: (1) the female sex pheromone contained 2 isomers, i. e. E9-12:Ac and Z9-12:Ac; and (2) the sex pheromone production of females had a diel periodicity. The female moths began to produce sex pheromone at the onset of the scotophase and the quantity increased gradually. Pheromone production peak occurred at the 6.5 h of the 2nd scotophase, and the pheromone titers released by females of various generations are different. The pheromone titer released by females of the overwintering generation or the 2nd generation was much higher than that of the 1st generation, but the ratios of the 2-isomeric components in different generations were the same.

Han, Guibiao published the artcileBehavioral response of male Ancylis sativa to sex pheromone, Recommanded Product: (Z)-Dodec-9-en-1-yl acetate, the publication is Kunchong Xuebao (2001), 44(2), 176-181, database is CAplus.

The behavioral response of individual male Ancylis sativa Liu to synthetic sex pheromone components, E9-12:Ac and Z9-12:Ac was observed in a wind tunnel. The lures containing only E9-12:Ac could stimulate males to perform all the typical behaviors including excitation, taking off, flying upwind, landing on the lure and exhibiting their hairpencils, while none of them showed any response to Z9-12:Ac. 71.7-76.7% Of the males displayed their hairpencils in response to the mixture of these two components (E accounting for 60-65%). The pheromone (E:Z=6.5:3.5) from 200 ng to 2000 ng per lure caused more male response than that of 20 ng or 20000 ng.

Gao, Jie published the artcileAmbient Hydrogenation and Deuteration of Alkenes Using a Nanostructured Ni-Core-Shell Catalyst, Recommanded Product: Methyl 3-phenyl-2-propenoate, the publication is Angewandte Chemie, International Edition (2021), 60(34), 18591-18598, database is CAplus and MEDLINE.

A general protocol for the selective hydrogenation and deuteration of a variety of alkenes is presented. Key to success for these reactions is the use of a specific nickel-graphitic shell-based core-shell-structured catalyst, which is conveniently prepared by impregnation and subsequent calcination of nickel nitrate on carbon at 450 °C under argon. Applying this nanostructured catalyst, both terminal and internal alkenes, which are of industrial and com. importance, were selectively hydrogenated and deuterated at ambient conditions (room temperature, using 1 bar hydrogen or 1 bar deuterium), giving access to the corresponding alkanes and deuterium-labeled alkanes in good to excellent yields. The synthetic utility and practicability of this Ni-based hydrogenation protocol is demonstrated by gram-scale reactions as well as efficient catalyst recycling experiments

Quan, Qinzhi published the artcileVisible-Light-Enabled Organocatalyzed Controlled Alternating Terpolymerization of Perfluorinated Vinyl Ethers, Computed Properties of 3052-61-7, the publication is Angewandte Chemie, International Edition (2021), 60(37), 20443-20451, database is CAplus and MEDLINE.

Polymerizations of perfluorinated vinyl ethers (PFVEs) provide an important category of fluoropolymers that have received considerable interests in applications. In this work, we report the development of an organocatalyzed controlled radical alternating terpolymn. of PFVEs and vinyl ethers (VEs) under visible-light irradiation This method not only enables the synthesis of a broad scope of fluorinated terpolymers of low dispersities and high chain-end fidelity, facilitating tuning the chem. compositions by rationally choosing the type and/or ratio of comonomers, but also allows temporal control of chain-growth, as well as the preparation of a variety of novel fluorinated block copolymers. To showcase the versatility of this method, fluorinated alternating terpolymers were synthesized and customized to simultaneously display a variety of desirable properties for solid polymer electrolyte design, creating new opportunities in high-performance energy storage devices.

Wu, Yu-Shen published the artcileManipulating the structures and photoresponsive properties of an azobenzene-containing triblock copolymer by changing solvency and adding salts, Computed Properties of 135529-02-1, the publication is Journal of Molecular Liquids (2022), 118013, database is CAplus.

We examined the structure-property relationship of a triblock copolymer comprising azobenzene sequences, namely, poly(6-[4-(4′-ethoxyphenylazo)phenoxy]hexyl methacrylate)-block-poly(ethylene glycol)-block-poly(6-[4-(4′-ethoxyphenylazo)phenoxy]hexyl methacrylate) (PMMAzo-b-PEG-b-PMMAzo), in mixed DMF (DMF)/H2O solvents, with the effects of solvency and salts being the main focus. When H2O (a PEG-selective solvent) was added to DMF (a neutral solvent), the poor compatibility between H2O and PMMAzo mols. led to the formation of micelles comprising PMMAzo and PEG in the core and corona, resp. Increases in the H2O content in the mixed solvent decreased the solvency, which caused increases in the micelle association number and hydrophobic core radius. The azobenzene moieties confined in the micellar core inhibited their photoisomerization, which caused decreases in the photoisomerization kinetics and cis isomer content. The addition of KCl to the PMMAzo-b-PEG-b-PMMAzo solution increased the hydrophobicity of PEG chains and the core radius and decreased the corona thickness. Moreover, the KSCN addition to the aforementioned solution increased the hydrophilicity of PMMAzo segments, which caused the core radius and corona thickness of micelles. Salt addition disturbed the compact packing of mesogens and reduced the mesogen association Consequently, with an increase in the salt concentration, the content of H-type mesogen aggregates increased, whereas that of nonassocd. mesogens decreased.

Ma, Cong-Xuan published the artcileDesign, synthesis and structure-activity relationships of novel macrolones: Hybrids of 2-fluoro 9-oxime ketolides and carbamoyl quinolones with highly improved activity against resistant pathogens, Product Details of C7H13NO2, the publication is European Journal of Medicinal Chemistry (2019), 1-20, database is CAplus and MEDLINE.

Constitutively erythromycin-resistant apathogens are more difficult to address than inducible resistant and efflux-resistant strains. Three series of the 4th generation 2-fluoro 9-oxime erythromycin ketolides were synthesized and evaluated. Incorporation of substituted heteroaryl groups, in contrast to previously reported the unsubstituted heteroaryl groups, proved to the beneficial for enhancement of the activities of the 9-propargyl ketolide 8 series and the 9-allyl ketolide 14 series. Structure-activity relationships and mol. modeling indicated that some title compounds may have different binding sites compared to current erythromycins. These findings pave the way for rational design of novel non-telithromycin macrolides that target new binding sites within bacterial ribosomes.

Qin, Tao published the artcileCobalt-Catalyzed Radical Hydroamination of Alkenes with N-Fluorobenzenesulfonimides, Synthetic Route of 103-26-4, the publication is Angewandte Chemie, International Edition (2021), 60(49), 25949-25957, database is CAplus and MEDLINE.

An efficient and general radical hydroamination of alkenes using Co(salen) as catalyst, N-fluorobenzenesulfonimide (NFSI) and its analogs as both nitrogen source and oxidant was successfully disclosed. A variety of alkenes, including aliphatic alkenes, styrenes, α, β-unsaturated esters, amides, acids, as well as enones, were all compatible to provide desired amination products. Mechanistic experiments suggest that the reaction underwent a metal-hydride-mediated hydrogen atom transfer (HAT) with alkene, followed by a pivotal catalyst controlled SN₂-like pathway between in-situ generated organocobalt(IV) species and nitrogen-based nucleophiles. Moreover, by virtue of modified chiral cobalt(II)-salen catalyst, an unprecedented asym. version was also achieved with good to excellent level of enantiocontrol. This novel asym. radical C-N bond construction opened a new door for the challenging asym. radical hydrofunctionalization.
