Chang, Chun-Wei; Lin, Mei-Huei; Wu, Chia-Hui; Chiang, Tsun-Yi; Wang, Cheng-Chung published the artcile< Mapping Mechanisms in Glycosylation Reactions with Donor Reactivity: Avoiding Generation of Side Products>, Application In Synthesis of 128-09-6, the main research area is glycosylation thioglycoside mechanism side product formation.

The glycosylation reaction, which is key for the studies on glycoscience, is challenging due to its complexity and intrinsic side reactions. Thioglycoside is one of the most widely used glycosyl donors in the synthesis of complex oligosaccharides. However, one of the challenges is its side reactions, which lower its yield and limits its efficiency, thereby requiring considerable effort in the optimization process. Herein, we reported a multifaceted exptl. approach that reveals the behaviors of side reactions, such as the intermol. thioaglycon transformation and N-glycosyl succinimides, via the glycosyl intermediate. Our mechanistic proposal was supported by low temperature NMR studies that can further be mapped by utilizing relative reactivity values. Accordingly, we also presented our findings to suppress the generation of side products in solving this particular problem for achieving high-yield glycosylation reactions.

Gu, Ai-Ling;Zhang, Ya-Xin;Wu, Zhi-Lei;Cui, Hui-Ya;Hu, Tian-Ding;Zhao, Bin research published 《 Highly Efficient Conversion of Propargylic Alcohols and Propargylic Amines with CO₂ Activated by Noble-Metal-Free Catalyst Cu₂O@ZIF-8》, the research content is summarized as follows. The cyclization reactions of propargylic alcs. and propargylic amines with CO₂ are important in industrial applications, but it was a great challenge that non-noble-metal catalysts catalyzed both reactions under mild conditions. Herein, the catalyst Cu₂O@ZIF-8 was prepared by encapsulating Cu₂O nanoparticles into robust ZIF-8, and it can effectively catalyze the cyclization of both propargylic alcs. and propargylic amines with CO₂ into valuable α-alkylidene cyclic carbonates and oxazolidinones with turnover numbers (TONs) of 12.1 and 19.6, which can be recycled at least five times. The mechanisms were further uncovered by NMR, FTIR, ¹³C isotope-labeling experiments and DFT calculations, in which Cu₂O and DBU can synergistically activate the C≃C bond and the hydroxy/amino group of substrates. Importantly, it is the first example of a noble-metal-free catalyst that can catalyze both propargylic alcs. and propargylic amines with CO₂ simultaneously.

Herein, the first structure-activity relationship studies of a series of novel nonpeptide amidinohydrazone-based agonists I [R¹ = H, 4-Me, 7-F, etc.; R² = H, Me; R³ = ; 4-ClC₆H₄, 3,4-di-ClC₆H₃, 2-thienyl, etc.; R⁴ = H, Me; n = 0,1,2,3], which were characterized by RXFP3 functional and radioligand binding assays was reported. Several potent and efficacious RXFP3 agonists compound I [R¹ = 5-CN-7-Me, R² = H, R³ = 4-CO₂MeC₆H₄, R⁴ = H, n = 2] were identified with EC₅₀ values <10 nM.

In vitro ADME and pharmacokinetic assessments revealed that the amidinohydrazone derivatives might have limited brain permeability.

Z.;Morrison, Finlay D.;Lee, Stephen L.;Lightfoot, Philip research published 《 Polarity and Ferromagnetism in Two-Dimensional Hybrid Copper Perovskites with Chlorinated Aromatic Spacers》, the research content is summarized as follows. Two-dimensional (2D) organic-inorganic hybrid copper perovskites have drawn tremendous attention as promising multifunctional materials. Herein, by incorporating ortho-, meta-, and para-chlorine substitutions in the benzylamine structure, we first report the influence of positional isomerism on the crystal structures of chlorobenzylammonium copper(II) chloride perovskites A₂CuCl₄. 2D polar ferromagnets (3-ClbaH)₂CuCl₄ and (4-ClbaH)₂CuCl₄ (ClbaH⁺ = chlorobenzylammonium) are successfully obtained. They both adopt a polar monoclinic space group Cc at room temperature, displaying significant differences in crystal structures. In contrast, (2-ClbaH)₂CuCl₄ adopts a centrosym. space group P2₁/c at room temperature This associated structural evolution successfully enhances the phys. properties of the two polar compounds with high thermal stability, discernible second harmonic generation (SHG) signals, ferromagnetism, and narrow optical band gaps. These findings demonstrate that the introduction of chlorine atoms into the interlayer organic species is a powerful tool to tune crystal symmetries and phys. properties, and this inspires further exploration of designing high-performance multifunctional copper-based materials.

Geng, Furong;Wu, Shaofeng;Gan, Xinyang;Hou, Wenjuan;Dong, Jianyu;Zhou, Yongbo research published 《 TEMPO mediated oxidative annulation of aryl methyl ketones with amines/ammonium acetate for imidazole synthesis》, the research content is summarized as follows. A facile synthesis of 1H-imidazoles I (R = Ph, pyridin-3-yl, thiophen-2-yl, etc.; R¹ = Ph, t-Bu, naphthalen-1-yl, etc.) by direct oxidative annulation of aryl Me ketones (RC(O)CH³) and primary amines R¹CH₂NH₂ has been developed in the presence of TEMPO under weakly acidic conditions. By replacing amines with ammonium acetate, 2H-imidazole skeletons II were achieved for the first time from ketones. Substrates containing various functional groups, such as alkyl, aryl, naphthyl, halogen (F, Cl, Br, I), nitro, trifluoromethyl, sulfonyl ester, furyl, thienyl, and pyridyl groups, were readily transformed into the desired products. The application potential of this method was verified by the scale-up synthesis and Sonogashira coupling functionalization of imidazoles I (R = R¹ = phenyl). Mechanistically, the α-TEMPO-enamine adduct may serve as the key reaction intermediate.

Gholivand, Khodayar;Barzegari, Azam;Mohammadpanah, Fahimeh;Yaghoubi, Rouhollah;Roohzadeh, Roohollah;Ebrahimi Valmoozi, Ali Asghar research published 《 Synthesis, characterized, QSAR studies and molecular docking of some phosphonates as COVID-19 inhibitors》, the research content is summarized as follows. The global coronavirus (COVID-19) outbreak has prompted scientists to discover a cure for the disease. So far, phosphorus-based drugs have been proposed. These drugs have good inhibitory activity against the main protease (Mpro). Hence, in order to introduce a group of inhibitors the coronavirus, 51 compounds containing different mono, bis, and tetra phosphonates as Remdesivir derivatives, 32 of which are new, were synthesized and characterized by ³¹P, ¹³C, and ¹H NMR and IR spectroscopy. Their biol. activities were also investigated by Mol. Docking, QSAR, and Pharmacophore. Van der Waals, hydrogen bonding, and hydrophobic interactions were studied for all compounds as well as binding energy (ΔG, Kcal/mol) and the inhibitory constant Ki (μM) obtained by Mol. Docking. The results showed that the topol. of the ligands and the change of the different groups attached to them can be effective in the placement position in the active site of the enzyme (Glu 166 and Gln 189). And bisphosphonates have a high interaction tendency with Mpro COVID-19. Compound L24 was identified as the best inhibitor with the -6.38 kcal/mol binding energy. The quant. structure-activity relationship (QSAR) findings demonstrated that the polarity and topol. of mols. in all phosphonate derivatives were important parameters affecting the effecting on the binding energy and inhibitory ability of compounds The DFT and pharmacophore results are in good accordance with those of QSAR and mol. docking. This study can be helpful to gain a better understanding of the interactions between the Mpro of virus and its inhibitors in order to attain drugs with more effect on coronavirus (COVID-19).
