To discover novel pesticide candidates, a series of sulfoximine derivatives were designed and synthesized via the oxidation coupling reaction of sulfides and N-alkyl nitroguanidines. The compounds were evaluated for their antifungal activity against six phytopathogenic fungi. Most of them exhibited a broad spectrum of fungicidal activity in vitro. Compound 8IV-b displayed good fungicidal activity against Sclerotinia sclerotiorum, Rhizoctonia solani, Botrytis cinerea, Fusarium graminearum, and Phytophthora capsici, with EC50 value of 12.82, 12.50, 17.25, 31.08, and 30.11 mg/L, resp. In addition, compounds 8III-c and 8IV-e had EC50 values of 22.23 and 20.67 mg/L against P. capsic, which were significantly better than that of the com. procymidone (118.15 mg/L). Strikingly, 8IV-d exhibited satisfactory fungicidal activity against B. cinerea, which was comparable to control procymidone in terms of their EC50 values (7.42 vs. 10.83 mg/L), and the bioassays in vivo further confirmed that 8IV-d possessed potent protective effect against B. cinerea at 200 mg/L (72.2 %). These present findings will facilitate the design and development of novel potent fungicides.

The chemo- and regioselective defluorinative [3 + 3] annulation of (trifluoromethyl)alkenes and pyrazolones was reported that gives rise to various useful 6-fluoro-1,4-dihydropyrano[2,3-c]pyrazoles I [R = Ph, 4-MeC₆H₄, 4-ClC₆H₄, etc.; R¹ = Ph, 3-MeC₆H₄, 4-ClC₆H₄, etc.; R² = Me, Et, Bn, etc.] in high yields. This reaction distinguished the different nucleophilic sites of pyrazolones and featured mild conditions, a broad substrate scope, and gram-scalability. A simple derivation of the obtained 6-fluoro-1,4-dihydropyrano[2,3-c]pyrazoles efficiently afforded diverse useful compounds Significantly, compound I [R = 4-F₃CC₆H₄, R¹ = 2-ClC₆H₄, R² = Me] exhibited up to 100% insecticidal activity against Plutella xylostella, which was a destructive pest worldwide. Mechanism studies indicated that this reaction proceeded via a chemo- and regioselective S_N2’/S_NV pathway and that the double defluorinative alkylation of pyrazolones with (trifluoromethyl)alkenes was completely inhibited.

He, Zhi-Tao published the artcileTrimethylphosphate as a Methylating Agent for Cross Coupling: A Slow-Release Mechanism for the Methylation of Arylboronic Esters, COA of Formula: C13H17BCl2O2, the publication is Journal of the American Chemical Society (2018), 140(49), 17197-17202, database is CAplus and MEDLINE.

Tri-Me phosphate acted as an effective source of Me groups; in the presence of CuI, and LiI, (MeO)₃P(:O) underwent chemoselective coupling with arylpinacolboronates mediated by LiOt-Bu in 1,3-dimethylimidazolidin-2-one (DMI) to yield methylarenes in higher yields than related coupling reactions using either Me iodide or Me tosylate. The methylation reaction was used in tandem with iridium-catalyzed regioselective borylation with bis(pinacolato)diboron to provide a one-pot methylation reaction for arenes, and for trideuteromethylation of arylpinacoboronates using tris(trideuteromethyl) phosphate. The chemoselectivity of the reaction was tested using additives possessing various functional groups (robustness screen); unprotected amines, alcs., and amides and terminal alkynes were not tolerated. The methylation of 1-naphthylpinacolboronate was demonstrated on a 200 mmol scale. The kinetics of the methylation and its dependence on Li⁺ and I^– ions was determined and a mechanism suggested. Me iodide is released slowly upon reaction of tri-Me phosphate with iodide; the low concentration of MeI enables selective reaction with arylcopper intermediates generated from the arylboronate rather than with other nucleophiles, while binding of tert-butoxide to the pinacolboronate reactants inhibits reaction of MeI with tert-butoxide.

Zhu, Chen published the artcileElusive Metal-Free Primary Amination of Arylboronic Acids: Synthetic Studies and Mechanism by Density Functional Theory, Related Products of chlorides-buliding-blocks, the publication is Journal of the American Chemical Society (2012), 134(44), 18253-18256, database is CAplus and MEDLINE.

Herein the authors disclose the first metal-free synthesis of primary aromatic amines from arylboronic acids, a reaction that has eluded synthetic chemists for decades. This remarkable transformation affords structurally diverse primary arylamines in good chem. yields, including a variety of halogenated primary anilines that often cannot be prepared via transition-metal-catalyzed amination. The reaction is operationally simple, requires only a slight excess of aminating agent [O-(2,4-dinitrophenyl)hydroxylamine], proceeds under neutral or basic conditions, and, importantly, can be scaled up to provide multigram quantities of primary anilines. D. functional calculations reveal that the most likely mechanism involves a facile 1,2-aryl migration, and that the presence of an ortho nitro group in the aminating agent plays a critical role in lowering the free energy barrier of the 1,2-aryl migration step.

Liu, Jing-Bo published the artcileSynthesis, insecticidal evaluation and 3D-QSAR study of novel anthranilic diamide derivatives as potential ryanodine receptor modulators, Formula: C6H3ClFNO2, the publication is Pest Management Science (2019), 75(4), 1034-1044, database is CAplus and MEDLINE.

BACKGROUND : Anthranilic diamide insecticides control lepidopteran pests through selectively binding and activating insect ryanodine receptors. In order to search for potential insecticides targeting the ryanodine receptors, a series of anthranilic diamide analogs including trifluoromethyl, nitro, or chloro groups were designed and synthesized by the principle of bioisosterism and structural optimization. RESULTS : Insecticidal data indicated that some compounds displayed good activity against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella). In particular, the larvicidal activity of 6p against P. xylostella was 95% at 0.01 mg L^-1, equivalent to chlorantraniliprole (85%, 0.01 mg L^-1). The comparative mol. similarity index anal. model obtained indicated that hydrogen bond acceptor and electron-withdrawing groups in the R’₃ group are favorable for insecticidal activity against M. separata, which is consistent with the structure-activity relationships. Moreover, the calcium imaging experiment indicated, like chlorantraniliprole, that 6h and 6p are interacting with the ryanodine receptor. CONCLUSION : Introducing trifluoromethyl, nitro, or chloro groups to a specific position in the N-phenylpyrazole could improve or maintain the activity against M. separata and P. xylostella. 6h and 6p could be used as potential lead compounds for ryanodine receptor modulators.Μ.

Liu, Jing-Bo published the artcileAnthranilic diamides derivatives as potential ryanodine receptor modulators: Synthesis, biological evaluation and structure activity relationship, HPLC of Formula: 1869-22-3, the publication is Bioorganic & Medicinal Chemistry (2018), 26(12), 3541-3550, database is CAplus and MEDLINE.

A series of novel anthranilic diamides derivatives (7a-s) containing halogen, trifluoromethyl group and cyano group were designed, synthesized, and characterized by m.p., ¹H NMR, ¹³C NMR and elemental analyses. The bioactivity revealed that most of them showed moderate to excellent activities against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella). Above all, the larvicidal activity of I against oriental armyworm was 100% and 40% at 0.25 and 0.1 mg L^-1, comparable to that of the standard chlorantraniliprole (100%, 0.25 mg L^-1 and 20%, 0.1 mg L^-1). What is more, 7o against diamondback moth displayed 90% insecticidal activity at 0.01 mg L^-1, superior to chlorantraniliprole (45%, 0.01 mg L^-1). The experiments I on the American cockroach (Periplaneta Americana) heart beating rates (Dorsal vessel) and contractile force were compared with chlorantraniliprole. In addition, I could affect the calcium homeostasis in the central neurons of the third larvae of oriental armyworm, which revealed that the ryanodine receptor is the potential target of I. The d. functional theory (DFT) calculation results revealed the amide bridge, the benzene ring of anthraniloyl moiety and pyrazole ring might play an important role in the insecticidal activity through hydrophobic interactions and π-π conjugations.
