Formula: C4H4INO2In 2019 ,《1,2-trans Glycosylation via Neighboring Group Participation of 2-O-Alkoxymethyl Groups: Application to One-Pot Oligosaccharide Synthesis》 was published in Organic Letters. The article was written by Karak, Milandip; Joh, Yohei; Suenaga, Masahiko; Oishi, Tohru; Torikai, Kohei. The article contains the following contents:

The use of 2-O-alkoxymethyl groups as effective stereo-directing substituents for the construction of 1,2-trans glycosidic linkages is reported. The observed stereoselectivity arises from the intramol. formation of a five-membered cyclic architecture between the 2-O-alkoxymethyl substituent and the oxocarbenium ion, which provides the expected facial selectivity. Furthermore, the observed stereocontrol and the extremely high reactivity of 2-O-alkoxymethyl-protected donors allowed development of a one-pot sequential glycosylation strategy that should become a powerful tool for the assembly of oligosaccharides. The results came from multiple reactions, including the reaction of 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Formula: C4H4INO2)

1-Iodopyrrolidine-2,5-dione(cas: 516-12-1) is used in the preparation of vinyl sulfones from olefins and benzenesulfinic acid.

Application of 63069-48-7In 2021 ,《Quasi-homogeneous catalytic conversion of CO2 into quinazolinones inside a metal-organic framework microreactor》 appeared in Green Chemistry. The author of the article were Zhou, Zhenzhen; Ma, Jian-Gong; Gao, Jianbo; Cheng, Peng. The article conveys some information:

Management of CO2 has been attracting great attention in this century. Reaction of CO2 with 2-haloanilines and isocyanides is an attractive way for both converting CO2 and producing quinazolinones, which are key intermediates for the synthesis of various biol. active products. However, the heterogeneous and relatively inert nature of CO2 with 2-haloaniline and isocyanide reactants limits the types of suitable catalysts. Herein, we use metal-organic frameworks (MOFs) as a “”microreactor””, in which Pd(PPh3)2Cl2 is well-dispersed as a single-mol. catalyst, and the reactants react in the mol. level through a “”quasi-homogeneous”” way to convert CO2 into quinazolinones under mild conditions with both promising yields over homogeneous catalysts and good recyclability as a heterogeneous reaction. The MOF-assisted single-mol. catalysis strategy should contribute to CO2 conversion, production of quinazolinone-type bioactive intermediates, and the epochal development of “”homo-and-heterogeneous”” catalysis. In addition to this study using 4-Chloro-2-iodoaniline, there are many other studies that have used 4-Chloro-2-iodoaniline(cas: 63069-48-7Application of 63069-48-7) was used in this study.

4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime. Amines have a free lone pair with which they can coordinate to metal centers. Amine–metal bonds are weaker because amines are incapable of backbonding, but they are still important for sensing applications.While stronger than hydrogen bonds, amine–metal bonds are still weaker than both covalent and ionic bonds.Application of 63069-48-7

Related Products of 15164-44-0In 2022 ,《Apoptotic mechanism in human brain microvascular endothelial cells triggered by 4′-iodo-α-pyrrolidinononanophenone: Contribution of decrease in antioxidant properties》 appeared in Toxicology Letters. The author of the article were Sakai, Yuji; Taguchi, Maki; Morikawa, Yoshifumi; Miyazono, Hidetoshi; Suenami, Koichi; Ochiai, Yuto; Yanase, Emiko; Takayama, Tomohiro; Ikari, Akira; Matsunaga, Toshiyuki. The article conveys some information:

In this study, four α-pyrrolidinononanophenone (α-PNP) derivatives [4′-halogenated derivatives and α-pyrrolidinodecanophenone (α-PDP)] were synthesized, and then performed the structure-cytotoxicity relationship analyses. The results showed the rank order for the cytotoxic effects, α-PNP < α-PDP < 4'-fluoro-α-PNP < 4'-chloro-α-PNP < 4'-bromo-α-PNP < 4'-iodo-α-PNP (I-α-PNP), and suggest that cytotoxicities of 4'-halogenated derivatives were more intensive than that of elongation of the hydrocarbon chain (α-PDP). The apoptotic mechanism of I-α-PNP was also surveyed in brain microvascular endothelial (HBME) cells that are utilized as the in-vitro model of the blood-brain barrier. HBME cell treatment with I-α-PNP facilitated the apoptotic events (caspase-3 activation, externalization of phosphatidylserine, and DNA fragmentation), which were almost completely abolished by pretreating with antioxidants. In addition, the immunofluorescent staining revealed the enhanced production of hydroxyl radical in mitochondria by the I-α-PNP treatment, inferring that the I-α-PNP treatment triggers the apoptotic mechanism dependent on the enhanced ROS production in mitochondria. The treatment with I-α-PNP increased the production of cytotoxic aldehyde 4-hydroxy-2-nonenal and decreased the amount of reduced glutathione. Addnl., the treatment decreased the 26S proteasome-based proteolytic activities and aggresome formation. These results suggest that decrease in the antioxidant properties is also ascribable to HBME cell apoptosis elicited by I-α-PNP.

In 2022,Kang, Kang; Li, Lei; Zhang, Meiyu; Miao, Xiaohe; Lei, Lecheng; Xiao, Chengliang published an article in Inorganic Chemistry. The title of the article was 《Two-Fold Interlocking Cationic Metal-Organic Framework Material with Exchangeable Chloride for Perrhenate/Pertechnetate Sorption》.Product Details of 15854-87-2 The author mentioned the following in the article:

Albeit reported substantial sorbents for elimination of TcO4-, the issue of secondary contamination caused by released counterions (such as NO3-) from the cationic metal-organic framework (MOF) has not come into the sufficient limelight for researchers. Herein, our efforts are dedicated to settle the matter through synthesis of NiCl2 based on the cationic MOF (ZJU-X4). Less harmful chlorides are used as exchangeable anions for replacing hazardous anions. Notably, ZJU-X4 exhibited fast sorption kinetics, high sorption capacity of 395 mg/g, decent selectivity, and excellent reusability in four recycles. The results of ion chromatog. revealed that the released chloride ion was equal to sorption of target ions, and pair distribution functions were employed to analyze the changes in ZJU-X4 after sorption of ReO4-, clearly elucidating the anion-exchange mechanism. Furthermore, in the dynamic sorption experiments, ReO4- could be facilely and effectively removed and recovered, showing the value of practical applications. This work indicated that cationic MOF-based metal chloride salts would be a better choice for anionic sorbents.
