A method for regioselective ring openings of 3,4- and 2,3-epoxy alcs. with ambident nitrogen heterocycles is described. Using a diarylborinic acid catalyst, a single regioisomer is favored in couplings of nucleophile and electrophile partners that display low regioselectivity under conventional conditions. The method provides access to aromatic heterocycles bearing stereochem. defined, functionalized alkyl substituents, a product class similar in structure to medicinally relevant compounds such as the acyclic nucleoside analogs. In the experimental materials used by the author, we found 1H-1,2,3-Triazole(cas: 288-36-8Product Details of 288-36-8)

1H-1,2,3-Triazole(cas: 288-36-8) belongs to triazoles. Triazoles are an important group of nitrogen-containing five-membered heterocyclic scaffolds.

Adhikari, Surya B.; Chen, Anji; Wang, Guijun published their research in Molecules in 2021. The article was titled 《Synthesis of carbohydrate based macrolactones and their applications as receptors for ion recognition and catalysis》.Related Products of 510758-28-8 The article contains the following contents:

Glycomacrolactones exhibit many interesting biol. properties, and they are also important in mol. recognitions and for supramol. chem. Therefore, it is important to be able to access glycomacrocycles with different sizes and functionality. A new series of carbohydrate-based macrocycles containing triazole and lactone moieties have been designed and synthesized. The synthesis features an intramol. nucleophilic substitution reaction for the macrocyclization step. In this article, the effect of some common sulfonate leaving groups is evaluated for macrolactonization. Using tosylate gave good selectivity for monolactonization products with good yields. Fourteen different macrocycles have been synthesized and characterized, of which eleven macrocycles are from cyclization of the C1 to C6 positions of N-acetyl D-glucosamine derivatives and three others from C2 to C6 cyclization of functionalized D-glucosamine derivatives These novel macrolactones have unique structures and demonstrate interesting anion binding properties, especially for chloride. The macrocycles containing two triazoles form complexes with copper sulfate, and they are effective ligands for copper sulfate mediated azide-alkyne cycloaddition reactions (CuAAC). In addition, several macrocycles show some selectivity for different alkynes. The results came from multiple reactions, including the reaction of Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8Related Products of 510758-28-8)

Safety of 1H-1,2,3-TriazoleIn 2020 ,《Insights into the lithium diffusion process in a defect-containing porous crystalline POM@MOF anode material》 appeared in Dalton Transactions. The author of the article were Zhu, Peipei; Yang, Xiya; Li, Xiao; Sheng, Ning; Zhang, Haifeng; Zhang, Gongguo; Sha, Jingquan. The article conveys some information:

Rechargeable lithium-ion batteries (LIBs) for potentially low-cost and high-energy-d. storage have been intensively researched to meet ever-growing demands. Achieving higher storages and understanding the transporting and storing diffusion process of Li ions are still great challenges. Herein, a porous crystalline polyoxometalate-based metal-organic framework (POM@MOF), H2[CuII4(Htrz)5(H2O)2][MoVI4CuII4O26]0.5·3H2O, with defect sites as a LIB electrode material is reported. The Li-ion diffusion process in the material was investigated using ex situ XPS and off-line powder X-ray diffraction (PXRD), indicating that O atoms of POM nano-clusters can be regarded as Li-ion acceptors (storage sites); meanwhile the defect sites (uncoordinated N atoms or -N-H groups) in the crystalline material also participate in the Li-ion storage. The reported porous crystalline POM@MOF material with defects delivers a remarkable Li-ion storage capacity of ca. 700 mA h g-1 in 200 cycles at a c.d. of 100 mA g-1.

Synthetic Route of C30H30N10In 2020 ,《Developing substrate-based small molecule fluorescent probes for super-resolution fluorescent imaging of various membrane transporters》 was published in Nanoscale Horizons. The article was written by Wu, Qiang; Cai, Mingjun; Gao, Jing; Zhao, Tan; Xu, Haijiao; Yan, Qiuyan; Jing, Yingying; Shi, Yan; Kang, Chuanqing; Liu, Yi; Liang, Feng; Chen, Junling; Wang, Hongda. The article contains the following contents:

Super-resolution imaging technol. has been a powerful tool for revealing fine biol. structures and functions. Its high-quality imaging always needs highly accurate labeling. Here, by exploiting the high specificity and affinity of natural substrates to transporters, we developed one set of substrate-based small mol. fluorescent probes for labeling membrane transporters. A glucose-based probe (Glu-probe) and tyrosine-based probe (Tyr-probe) were synthesized as two examples. Confocal imaging showed that the Glu-probe could label glucose transporters on live cells by being stuck into the binding site. Compared with antibody-probe labeling, the labeling advantages of the Glu-probe were revealed. High specificity of the Glu-probe or Tyr-probe was examined by a colocalization experiment and glucose replacement or amino acid (AA) blocking. The synthetic probes were also tested on imaging HeLa cells to confirm their wide labeling application. Addnl., we found that membrane transporters were mostly in the clustered state on cellular membranes, changing their assembly pattern to regulate the transport effectiveness. These results suggest that the substrate-based probes can serve as valuable tools for investigating the spatial information of membrane transporters.Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8Synthetic Route of C30H30N10) was used in this study.

The widespread application of 1,2,3-triazoles in pharmaceuticals has resulted in substantial interest toward developing efficient postmodification methods. Whereas there are many postmodification methods available to obtain N1-substituted 1,2,3-triazoles, developing a selective and convenient protocol to synthesize N2-aryl-1,2,3-triazoles has been challenging.

《An AIE+TICT activated colorimetric and ratiometric fluorescent sensor for portable, rapid, and selective detection of phosgene》 was written by Hu, Qinghua; Huang, Qiuxiang; Liang, Kexin; Wang, Yuyuan; Mao, Yu; Yin, Qiang; Wang, Hongqing. Application In Synthesis of Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine And the article was included in Dyes and Pigments in 2020. The article conveys some information:

Colorless, highly toxic phosgene is long considered a great menace to human health and national security. An excellent aggregation-induced emission (AIE) + TICT characteristic ratiometric colorimetric fluorescent sensor, TPE-CI, was constructed by combining a TICT-based 3-benzo[d]imidazole-chromen-2-imine with an AIE-based tetraphenylethene (TPE) unit. A TPE-CI probe detects phosgene in organic solvents by a change from the TICT process to the AIE process, but also in solids by a new change from the AIE + TICT process to the AIE process. TPE-CI exhibited convenient use as a test strip with rapid response (<6 s in solvent; 2 min in air atm.) and excellent and fair sensitivities for visual inspection of trace phosgene in organic solvents and as a gas. A calculated limit of detection was 0.36μM in solvent and 0.27 ppm in air, far below the acute phosgene exposure level for human response. Satisfactory results indicated this AIE + TICT strategy may offer valuable thinking to develop convenient solid-state optical sensors with dual ratiometric and colorimetric fluorescence response for gaseous phosgene identification.
