Proton chemical shifts in substituted methyl pyridinecarboxylates.Related Products of 26218-78-0.

The chem. shifts in 6 series of substituted Me pyridinecarboxylates were measured and interpreted in terms of proximity effects. The shifts for ring H ortho and para to the substituent were explained by additive ester, nitrogen, and substituent effects. The results for meta H indicated substituent-nitrogen interactions, especially when both substituent and H were adjacent N. Similar results were obtained for the ester H.

Category: tetrahydrofurans. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Methyl 6-bromonicotinate, is researched, Molecular C7H6BrNO2, CAS is 26218-78-0, about Modulation of Topological Structures and Adsorption Properties of Copper-Tricarboxylate Frameworks Enabled by the Effect of the Functional Group and Its Position. Author is Lin, Shengjie; Zhou, Ping; Xu, Tingting; Fan, Lihui; Wang, Xinxin; Yue, Lianglan; Jiang, Zhenzhen; Zhang, Yuanbin; Zhang, Zhengyi; He, Yabing.

To push forward the structural development and fully explore the potential utility, it is highly desired but challenging to regulate in a controllable manner the structures and properties of MOFs. The authors reported the structural and functional modulation of Cu(II)-tricarboxylate frameworks by employing a strategy of engineering the functionalities and their positions. Two pairs of unsym. biaryl tricarboxylate ligands modified with a Me group and a pyridinic-N atom at distinct positions were logically designed and synthesized, and their corresponding Cu(II)-based MOFs were solvothermally constructed. Diffraction analyses revealed that the variation of functionalities and their positions furnished three different types of topol. structures, which the authors ascribed to the steric effect exerted by the Me group and the chelating effect involving the pyridinic-N atom. Also, gas adsorption studies showed that three of them are potential candidates as solid separation media for acetylene (C2H2) purification, with the separation potential tailorable by altering functionalities and their locations. At 106.7 kPa and 298 K, the C2H2 uptake capacity varies from 64.1 to 132.4 cm3 (STP) g-1, while the adsorption selectivities of C2H2 over its coexisting components of CO2 and CH4 fall at 3.28-4.60 and 14.1-21.9, resp.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 26218-78-0, is researched, Molecular C7H6BrNO2, about Functionalization of bis-diazaphospholene P-P bonds with diverse electrophiles, the main research direction is functionalization diazaphospholene dimer electrophile; phosphorus bond cleavage diazaphospholene dimer electrophile; crystal mol structure diazaphospholene dimer functionalized product.Electric Literature of C7H6BrNO2.

Readily prepared bis-diazaphospholenes are shown to react with several classes of electrophiles, resulting in cleavage of the phosphorus-phosphorus bond and formation of functionalized diazaphospholenes. Phosphorus – sp3 or sp2 carbon and phosphorus – sulfur bonds were formed using this protocol. Exptl. evidence with aryl and alkyl halides suggests the intermediacy of radicals in some cases, however other evidence suggests either radical or polar mechanisms may be operative for certain substrates, with a dependence on reaction conditions. In some cases, the substituted diazaphospholenes can transfer the substituent to electrophiles via previously unknown reactions. These results show diazaphospholene dimers are potent participants in radical chem. at room temperature without requiring chem. initiators.

We report a method for the synthesis of chiral vicinal chloroamines via asym. protonation of catalytically generated prochiral chloroenamines using chiral Bronsted acids. The process is highly enantioselective, with the origin of asymmetry and catalyst substituent effects elucidated by DFT calculations We show the utility of the method as an approach to the synthesis of a broad range of heterocycle-substituted aziridines by treatment of the chloroamines with base in a one-pot process, as well as the utility of the process to allow access to vicinal diamines.

The synthesis, characterization and photophys. characteristics of the first iridium(III) complex with a caged ligand structure is reported. Thus, treating tripodal ligand (I) with 1 equiv of IrCl3·H2O and 3 equiv of CF3CO2Ag in refluxing ethylene glycol yielded, upon addition of LiOH and esterification with excess trimethylsilyldiazomethane, the iridium(III) hemicaged Me ester derivative II in 20% yield. Subsequently, II was hydrolyzed with LiOH and then subjected to DCC/HOBt (DCC = N,N’-dicyclohexylcarbodiimide, HOBt = hydroxybenzotriazole) coupling with tris(2-aminoethyl)amine, yielding the iridium(III) cage complex III in 22% yield. Iridium cage complex III shows an 80% decrease of oxygen quenching with respect to the archetypical Ir(ppy)3 (ppy = 2-phenylpyridyl), based on the Stern-Volmer plots of the three iridium complexes.

A catalytic enantioselective synthesis of heterocyclic vicinal fluoroamines such as I [Ar = Ph, 2-FC6H4, benzo[b]thiophenyl, etc.; Ar1 = quinolin-2-yl, quinoxalin-2-yl, benzo[d]thiazol-2-yl, etc.] is reported. A chiral Bronsted acid promotes aza-Michael addition to fluoroalkenyl heterocycles to give a prochiral enamine intermediate that undergoes asym. protonation upon rearomatization. The reaction accommodates a range of azaheterocycles and nucleophiles, generating C-F stereocenter in high enantioselectivity, and is also amenable to stereogenic C-CF3 bonds. Extensive DFT calculations provided evidence for stereocontrolled proton transfer from catalyst to substrate as rate-determining step, and showed importance of steric interactions from catalyst’s alkyl groups in enforcing high enantioselectivity. Crystal structure data show dominance of noncovalent interactions in core structure conformation, enabling modulation of conformational landscape. Ramachandran-type anal. of conformer distribution and Protein Data Bank mining indicated that benzylic fluorination by this approach has potential to improve potency of several marketed drugs.

A flow-based synthesis of diversely functionalized indolizines and their aza-analogs is described. These drug-like heterocycles were generated via a tandem Sonogashira/cycloisomerization sequence, starting from widely available 2-bromopyridines and alkynes, employing a simple catalyst system together with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as base. E.g., in presence of PdCl2(PPh3)2, CuI, and NEt3, followed by addition of DBU in DMF, Sonogashira/cycloisomerization of Me 6-bromonicotinate and N-methyl-N-propargylbenzylamine gave 71% indolizine derivative (I).
