Plant bacterial diseases cause tremendous decreases in crop yield and quality, and there is a lack of highly effective and low-risk antibacterial agents. A series of novel pyrido[1,2-a]pyrimidinone mesoionic compounds containing vanillin moieties were synthesized, and the application of these mesoionic compounds as plant antibacterial agents was reported here for the first time. The bioassay results revealed that the mesoionic compounds had good antibacterial activity. Of these compounds, compound (I) showed excellent in vitro activity against Xanthomonas oryzae pv. oryzae, with an EC₅₀ value of 1.1μg/mL, which was substantially better than that of bismerthiazol (92.7μg/mL) and thiodiazole copper (105.4μg/mL). Moreover, greenhouse condition trials indicated that the protective and curative activities of compound I against rice bacterial leaf blight were 75.12% and 72.04%, resp., which were better than those of bismerthiazol (62.24% and 50.83%, resp.) and thiodiazole copper (53.35% and 65.04%, resp.). These results provide a basis for the application of mesoionic vanillin moieties as new antibacterial agents.

Ye, Zenghui published the artcilePIDA-Mediated Rearrangement for the Synthesis of Enantiopure Triazolopyridinones, Name: Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate, the publication is Organic Letters (2020), 22(16), 6464-6467, database is CAplus and MEDLINE.

A tandem oxidative cyclization/1,2-carbon migration of hydrazides for the synthesis of otherwise inaccessible hindered or enantiopure triazolopyridinones has been developed. This protocol exhibits broad substrate scope and can be easily scaled up by continuous flow synthesis under mild conditions. Most importantly, this method demonstrates a rearrangement with retention of configuration and can be readily applied for the late-stage modification of carboxylic-acid-containing pharmaceuticals, amino acids, and natural products to access enantiopure triazolopyridinones.

The luminescent measurements indicate the typical emissions of corresponding Ln³⁺ ions in complexes 1–4. Furthermore, complexes 2 and 4 display significant luminescent response for Fe³⁺ ions with high quenching constant Complexes 2 and 4 can act as luminescent probes for Fe³⁺ ions with relatively high sensitivity and selectivity.

Qi, Jing published the artcileNew Radical Borylation Pathways for Organoboron Synthesis Enabled by Photoredox Catalysis, Category: chlorides-buliding-blocks, the publication is Angewandte Chemie, International Edition (2020), 59(31), 12876-12884, database is CAplus and MEDLINE.

Radical borylation using N-heterocyclic carbene (NHC)-BH₃ complexes as boryl radical precursors has emerged as an important synthetic tool for organoboron assembly. However, the majority of reported methods are limited to reaction modes involving carbo- and/or hydroboration of specific alkenes and alkynes. Moreover, the generation of NHC-boryl radicals relies principally on hydrogen atom abstraction with the aid of radical initiators. A distinct radical generation method is reported, as well as the reaction pathways of NHC-boryl radicals enabled by photoredox catalysis. NHC-boryl radicals are generated via a single-electron oxidation and subsequently undergo cross-coupling with the in-situ-generated radical anions to yield gem-difluoroallylboronates. A photoredox-catalyzed radical arylboration reaction of alkenes was achieved using cyanoarenes as arylating components from which elaborated organoborons were accessed. Mechanistic studies verified the oxidative formation of NHC-boryl radicals through a single-electron-transfer pathway.

Lu, Tao published the artcileSynthesis and photochromism of dithienylethene-based isocyanide and gold (I) complexes with various alkyl chains, Quality Control of 219537-97-0, the publication is Dyes and Pigments (2021), 108964, database is CAplus.

The development of novel dithienylethene-based complexes is highly desirable for potential application in the photoresponsive optoelectronics. In this contribution, the authors designed and prepared four novel dithienylethene-containing isocyanides 9a–9d and their binuclear Au(I) complexes 3a–3d with various alkyl chains. They were fully characterized and confirmed by ¹H NMR, ¹³C NMR, ¹⁹F NMR, and HRMS (ESI-TOF). Upon alternating irradiation with UV light at 302 nm and visible light at 530 nm, these isocyanides and corresponding Au(I) complexes displayed good photochromic behavior. And the slight effect of the length of alkyl chains on photochromic properties of these isocyanides and Au(I) complexes was observed Also, compared to the precursors 9a–9d, their Au(I) complexes 3a–3d showed higher molar absorptivities for ring-open isomers, closing rate and cycloreversion quantum yields. Au(I) complexes displayed much more excellent fatigue resistance compared with that of isocyanides. Accordingly, these results further proved the formation of Au(I) complexes can promote photochromic behavior to some extent.

Fu, Ying published the artcileDiscovery of N-Aroyl Diketone/Triketone Derivatives as Novel 4-Hydroxyphenylpyruvate Dioxygenase Inhibiting-Based Herbicides, Application In Synthesis of 3919-74-2, the publication is Journal of Agricultural and Food Chemistry (2019), 67(43), 11839-11847, database is CAplus and MEDLINE.

4-Hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, HPPD) is one of the most promising targets for the discovery of new bleaching herbicides. To discover novel HPPD inhibitors with excellent herbicidal activity, a series of novel N-aroyl diketone/triketone derivatives were rationally designed by splicing active groups and bioisosterism. All the compounds were characterized by IR, ¹H and ¹³C NMR, and high-resolution mass spectrometry. Bioassays revealed that most of these derivatives displayed preferable herbicidal activity against Echinochloa crus-galli at 0.045 mmol/m² and Abutilon juncea at 0.090 mmol/m². In particular, compound (I) was more potent compared with the commercialized compound mesotrione. Mol. docking indicated that the corresponding active mols. of target compounds and mesotrione shared similar interplay with surrounding residues, which led to a perfect interaction with the active site of Arabidopsis thaliana HPPD. These promising findings demonstrate that these compounds could be considered as potential herbicide candidates for further development of novel HPPD inhibitors.

Tian, Ze-Yu published the artcileVisible-light-initiated catalyst-free trifluoromethylselenolation of arylsulfonium salts with [Me₄N][SeCF₃], SDS of cas: 637-07-0, the publication is Organic Chemistry Frontiers (2022), 9(8), 2220-2227, database is CAplus.

The redox potential gap between arylsulfonium salts and [Me₄N][SeCF₃] has been clearly revealed by CV measurements. Construction of the carbon-selenium bond by overcoming this gap without using catalysts and additives is a challenging task. Here, the authors report an efficient visible-light-induced cross-coupling of arylsulfonium triflates, e.g., 5-[4-(4-cyanophenoxy)phenyl]-5H-thianthren-5-ium triflate, with [Me₄N][SeCF₃] by simply mixing these two species, which allowed the facile synthesis of various aryl trifluoromethyl selenoethers, e.g., ArSeCF₃ (Ar = 2-formyl-4-methoxyphenyl, N-methylcarbazol-6-yl, benzodioxol-5-yl, etc.) under catalyst- and additive-free conditions. The mechanistic study indicated that aryl and SeCF₃ radicals might be formed as key intermediates in the reactions. Merits of the reactions include operational simplicity, high efficiency, visible-light irradiation, good functional group tolerance, a wide range of substrates, excellent chemoselectivity, and good yields of (trifluoromethyl)selenolated products, which combined with a sulfenylation process enabled the selective and practical installation of SeCF₃ moieties onto complex arenes, including drug mols., via a formal C-H functionalization.

A sym. diarylethene containing N-salicylideneaniline (Schiff base) units was synthesized. The structure was well confirmed by NMR spectroscopy, mass spectrometry, and elemental anal. Its photochromism was investigated by UV/visible absorption spectra and NMR. The result displayed that diarylethene can well perform photoisomerization, but no obvious intramol. proton transfer was observed Furthermore, we checked the effects of metal cations for the properties of N-salicylideneaniline-based diarylethene, which indicated that Cu²⁺ and Fe³⁺ cations can significantly affect the UV/visible absorption spectra of diarylethene ring-open and ring-closed isomers.

Zhao, Xuelian published the artcileSynthesis and biological evaluation of isatin derivatives containing 1,3,4-thiadiazole as potent a-glucosidase inhibitors, Related Products of chlorides-buliding-blocks, the publication is Bioorganic & Medicinal Chemistry Letters (2021), 128447, database is CAplus and MEDLINE.

A series of isatin derivatives containing 1,3,4-thiadiazole derivatives I [R = 2-F, 3-CN, 4-Cl, etc.] were designed and synthesized. All newly synthesized compounds I were evaluated for their α-glucosidase inhibitory activity with resveratrol as pos. control in-vitro. Except for compounds I [R = 2-CN, 3-CN], all of the compounds I showed a potent inhibitory activity against α-glucosidase with IC₅₀ values in the range of 3.12 ± 1.25 to 45.95 ± 1.26μM and the purity of these compounds were greater than 95%. The IC₅₀ values were being compared to the standard resveratrol (IC₅₀ = 22.00 ± 1.15μM) and it was found that compounds I [R = H, 2-F, 2-Cl, 3-Cl, 4-Cl, 2-Br] were found to be more active than resveratrol. Specifically,I [R = 4-Cl] exhibited the most potent α-glucosidase inhibitory activity with IC₅₀ value of 3.12 ± 1.25μM. The kinetic anal. revealed that compound I [R = 4-Cl] was noncompetitive inhibitor. Structure activity relationship was established for all compounds I. Furthermore, the binding interactions of compound I [R = 4-Cl] with the active site of α-glucosidase were confirmed through mol. docking. This study was identified a new class of potent α-glucosidase inhibitors for further investigation.
