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.

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.

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.

A series of lanthanide coordination polymers (Ln-CPs), with the formula of {[Ln(L)₃(CH₃OH)(H₂O)]_n} (Ln = Sm (1), Eu (2), HL = 2-chloroisonicotinic acid) and {[Ln(L)₃(H₂O)₂]_n} (Ln = Dy (3), Tb (4)), were synthesized under solvothermal condition. This series display two different 1D chains due to the lanthanide contraction: complexes 1 and 2, based on light Sm and Eu, resp., consist of paddle-wheel [Ln₂(COO)₄] dimmers through double μ₂-COO bridges, and complexes 3 and 4 with heavy Dy and Tb, resp., show 1D [Ln(COO)₂]_n chains. 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.

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.

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.

An efficient parallel liquid-phase synthesis of pyrazolines I (R¹ = H, Me; R² = Ph, 4-MeOC₆H₄, 2-furyl; R³ = Ph, 4-MeC₆H₄, 4-FC₆H₄) has been developed. The one-pot three-component reaction of polyethylene glycol (PEG)-supported acrylate, arylaldehydes, and aryl hydrazines, in the presence of chloramine-T in methanol, gave the corresponding PEG-supported pyrazolines. Cleavage from the support under mild conditions afforded pyrazolines I in good yields and high purities.

Nan, Xiang published the artcileDesign, synthesis and biological evaluation of novel N-sulfonylamidine-based derivatives as c-Met inhibitors via Cu-catalyzed three-component reaction, Synthetic Route of 939-99-1, the publication is European Journal of Medicinal Chemistry (2020), 112470, database is CAplus and MEDLINE.

A series of new N-sulfonylamidine derivatives were designed, synthesized via Cu-catalyzed multicomponent reaction (MCR) as the key step, and evaluated for their in vitro biol. activities against c-Met kinase and four cancer cell lines (A549, HT-29, MKN-45 and MDA-MB-231). Most of the target compounds showed moderate to significant potency at enzyme and cell-based assay. The preliminary SAR studies demonstrated that compound I (c-Met IC₅₀ = 2.89 nM) was the most promising compound compared with the pos. foretinib, which exhibited the remarkable antiproliferative activities, with IC₅₀ values ranging from 0.28 to 0.72μM. Mechanistic studies of compound I showed the anticancer activity was closely related to the blocking phosphorylation of c-Met, leading to cell cycle arresting at G2/M phase and apoptosis of A549 cells by a concentration-dependent manner. The promising compound I was further identified as a relatively selective inhibitor of c-Met kinase, which also possessed an acceptable safety profile and favorable pharmacokinetic properties in BALB/c mouse. The favorable drug-likeness of I suggested that N-sulfonylamidines may be used as a promising scaffold for antitumor drug development. Addnl., the docking study and mol. dynamics simulations of I revealed a common mode of interaction with the binding site of c-Met. These pos. results indicated that I is a potential anti-cancer candidate for clin. trials, and deserves further development as a selective c-Met inhibitor.
