In order to find efficient, eco-friendly lead compounds, 10 novel phthalic acid diamide derivatives containing two trifluoromethylated aromatic amine moieties were designed and synthesized. Their structures were confirmed by 1H NMR, 13C NMR, HRMS and elemental anal. Their insecticidal activities against oriental armyworms and diamondback moths were also evaluated. The preliminary results of biol. evaluation showed that most compounds exhibited moderate to high larvicidal activity. These results provided further insights into the relationship between the structures and biol. activity.

An intermol. addition of carbon radicals enabled by a cascade radical coupling strategy is developed. It includes an intermol. alkyl radical addition to a carbonyl group followed by an intramol. alkoxy radical addition to haloarenes and produces substituted benzofurans in high yields. The radical nature of this reaction is explored by radical trapping experiments and EPR anal. The mechanism is investigated by KIE experiments and control experiments This method could provide rapid and practical access to the key intermediate of TAM-16, a safe and potent antibacterial agent for treating tuberculosis, and, therefore, is of great importance for organic synthesis and the pharmaceutical industry.

Sangouard, Gontran; Zorzi, Alessandro; Wu, Yuteng; Ehret, Edouard; Schuettel, Mischa; Kale, Sangram; Diaz-Perlas, Cristina; Vesin, Jonathan; Bortoli Chapalay, Julien; Turcatti, Gerardo; Heinis, Christian published the artcile< Picomole-Scale Synthesis and Screening of Macrocyclic Compound Libraries by Acoustic Liquid Transfer>, Related Products of 3959-07-7, the main research area is macrocycle compound acoustic liquid transfer MDM2 p53 PPI; acoustic droplet ejection; combinatorial synthesis; macrocycles; picomole scale; protein-protein interactions.

Macrocyclic compounds are an attractive class of therapeutic ligands against challenging targets, such as protein-protein interactions. However, the development of macrocycles as drugs is hindered by the lack of large combinatorial macrocyclic libraries, which are cumbersome, expensive, and time consuming to make, screen, and deconvolute. Here, we established a strategy for synthesizing and screening combinatorial libraries on a picomolar scale by using acoustic droplet ejection to combine building blocks at nanoliter volumes, which reduced the reaction volumes, reagent consumption, and synthesis time. As a proof-of-concept, we assembled a 2700-member target-focused macrocyclic library that we could subsequently assay in the same microtiter synthesis plates, saving the need for addnl. transfers and deconvolution schemes. We screened the library against the MDM2-p53 protein-protein interaction and generated micromolar and sub-micromolar inhibitors. Our approach based on acoustic liquid transfer provides a general strategy for the development of macrocycle ligands.

He, Peipei; Lv, Ying; Shang, Sensen; Chen, Bo; Liang, Hongliang; Niu, Jingyang; Dai, Wen published the artcile< Defect-Rich Core-Shell Carbon Derived from Ionic Liquid for Direct Synthesis of Imines>, Synthetic Route of 3959-07-7, the main research area is imine preparation; amine self cross coupling core shell carbon preparation catalyst; ionic liquid sodium tetraphenylborate electrostatic interaction.

Herein, ionic liquid 1-ethyl-3-methylimidazolium dicyanamide and sodium tetraphenylborate were employed as joint precursors to facilely prepare micro-mesoporous core-shell carbon with sp. surface area up to 2870 m2 g-1, consisting of smooth unpenetrated shell and secondary hollow spherical carbon core. The as-obtained core-shell carbon as metal-free catalyst exhibited good performance for self-coupling and cross-coupling of amines RCH2NH2 (R = Ph, furan-2-yl, cyclohexyl, etc.), R1NH2 (R1 = Ph, n-hexyl, cyclohexyl, etc.) to achieve the corresponding symmetry RCH=NCH2R and asymmetry imines RCH=NR1 under mild and neat conditions. Excitingly, for the challenging aliphatic amine cyclohexylmethanamine, the desired imines RCH=NCH2R (R = cyclohexyl) were achieved in 55.9% yield. The nearly linearly correlation between imine yield and ID/IG indicated that the resulting defects from departure of heteroatoms during pyrolysis may be active site.

Difluoreno[1,9,8-alkj:1′,9′,8′-gfed]heptalenes I (R = 2,4,6-Me3C6H2, 2,6-Me2-4-t-BuC6H2) were prepared in eight steps from fluoranthene. The structures of I (R = 2,4,6-Me3C6H2) and of the dication of I (R = 2,6-Me2-4-t-BuC6H2) were determined by X-ray crystallog. The oxidation and reduction potentials and UV/visible spectra of I (R = 2,4,6-Me3C6H2) and its dication were determined Calculations of the structure and aromaticity of I indicate that the planar core of I induces antiaromaticity and diradical character, in contrast with the isomeric bisanthene core.
