Rational molecular design of anion exchange membranes functionalized with alicyclic quaternary ammonium cations

High alkaline stability is critical for polymeric anion exchange membranes (AEMs) and ionomers for use in alkaline electrochemical energy conversion and storage devices such as fuel cells, electrolyzer cells and advanced batteries. Here, we have prepared and studied ether-free polyfluorenes tethered with N,N-dimethylpiperidinium (DMP) and 6-azonia-spiro[5.5]undecane (ASU) cations, respectively, attached through heteroatom-free alkyl spacers. By employing alkyl-alkyl Suzuki cross-coupling, these alicyclic quaternary ammonium cations are attached at the 4-position to impede ionic loss. Thus, all the beta-hydrogens sensitive to elimination reactions are placed in strain-free rings able to fully relax by the spacer flexibility. Consequently, the AEM carrying DMP cations shows a very high alkaline and thermal stability, retaining more than 91% of the cations after 2400 h immersion in 2 M NaOH at 90 degrees C. Compared with corresponding AEM functionalized with N-alkyl-N-methylpiperidinium (AMP) cations [conventionally tethered via the 1(N)-position], the ionic loss by beta-elimination is successfully reduced by up to 92%. The AEM functionalized with DMP also reaches a high hydroxide conductivity of 124 mS cm(-1) at 80 degrees C. Consequently, tethering piperidine-based cations via the 4-position instead of the 1(N)-position results in AEMs with substantially improved thermal and alkaline stability, combined with high hydroxide conductivity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 3056-33-5. Quality Control of N2,9-Diacetylguanine.

Inherent Flexibility vis-a-vis Structural Rigidity in Chemically Stable Antimalarial Dispiro N-Sulfonylpiperidine Tetraoxanes

Structurally diverse and chemically stable tetraoxanes were formed by peroxidation of N-sulfonylpiperidones. X-ray analysis revealed that the crystal structures possess central spiro-2,5-disubstituted tetraoxane rings trans fused to 6-membered piperidine and cyclohexylidene substituents in classical chair conformations. The more flexible cycloheptane ring exhibited pseudorotation between chair and twist chair conformation. The two sulfonyl oxygen atoms act as hydrogen-bonding acceptors and participate in hydrogen bonding. Docking calculations showed that the tetraoxanes are aligned parallel to the plane of the porphyrin ring of heme so that the iron can attack the O-O bond to initiate redox-mediated reaction to render nanomolar antimalarial potency to these compounds against P. falciparum 3D7.

SYNTHESIS OF TRIPEPTIDES CONTAINING HETEROCYCLIC alpha-AMINO ACIDS BY USING HETEROSPIROCYCLIC 3-AMINO-2H-AZIRINES

By using the ‘azirine/oxazolone method’, di- and tripeptides containing six-membered heterocyclic 4-amino-4-carboxylic acids with a piperidine, tetrahydropyran or tetrahydrothiopyran ring have been synthesized. It has been shown that the corresponding heterospirocyclic 3-(N-methyl-N-phenylamino)-2H-azirines are suitable synthons for these heterocyclic alpha-amino acids. As expected, the presence of these alpha,alpha-disubstituted alpha-amino acids stabilizes beta-turn conformations in the prepared tripeptides of type Z-Phe-Xaa-Val-OR.

Microwave-Assisted Synthesis, Structural Characterization and Assessment of the Antibacterial Activity of Some New Aminopyridine, Pyrrolidine, Piperidine and Morpholine Acetamides

A series of new acetamide derivatives 22-28 of primary and secondary amines and para-toluene sulphinate sodium salt have been synthesized under microwave irradiation and assessed in vitro for their antibacterial activity against one Gram-positive and two Gram-negative bacterial species such as S. pyogenes, E. coli, and P. mirabilis using the Mueller-Hinton Agar diffusion (well diffusion) method. The synthesized compounds with significant differences in inhibition diameters and MICs were compared with those of amoxicillin, ampicillin, cephalothin, azithromycin and doxycycline. All of the evaluated acetamide derivatives were used with varying inhibition concentrations of 6.25, 12.5, 37.5, 62.5, 87.5, 112.5 and 125 mu g/mL. The results show that the most important antibacterial properties were displayed by the synthetic compounds 22 and 24, both of bear a para-chlorophenyl moiety incorporated into the 2-position moiety of acetamide 1. The molecular structures of the new compounds were determined using the FT-IR and H-1-NMR techniques.

Synthesis of 1,4,5-Trisubstituted 1,2,3-Triazoles Through a One-Pot Three Component Reaction of Boronic Acids, Sodium Azide and Active Methylene Compounds Under Ball-Milling Conditions

In this study, we report a mild and efficient one-pot synthesis of 1,4,5-trisubstituted 1,2,3-triazoles via a three-component reaction of aryl boronic acids with sodium azide and active methylene compounds under ball-milling condition. In order to determine optimized reaction conditions, several grinding auxiliaries (basic, neutral and acidic alumina, silica gel, K10 and KSF), bases (DBU, DABCO, piperidine, triethylamine, potassium t-butoxide and potassium carbonate) and copper salts under ball-milling conditions were examined. Using the optimized condition procedure, a wide variety of 1,4,5-trisubstituted 1,2,3-triazole derivatives were prepared in very good yields. All products were well-characterized by H-1-NMR and C-13-NMR spectroscopy. This environmentally friendly protocol offers several advantages including high yields of products, relatively short reaction time and simple work-up procedure.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4395-98-6, in my other articles. Formula: C6H10N2.

Copper-catalyzed aerobic decarboxylative coupling between cyclic alpha-amino acids and diverse C-H nucleophiles with low catalyst loading

An aerobic decarboxylative cross-coupling of alpha-amino acids with diverse C-H nucleophiles has been realized using Cu-2(OH)(2)CO3 (1 mol%) as the catalyst under air. This protocol enables highly efficient formation of various C(sp(3))-C(sp(3)), C(sp(3))-C(sp(2)) and C(sp(3))-C(sp) bonds under simple conditions without the use of any ligand or extra oxidant, providing a practical approach to numerous nitrogen-containing compounds in good to excellent yields. The efficiency and practicability were also demonstrated by the gram-scale experiment and three-step synthesis of a Rad51 inhibitor.

Enantioselective Synthesis of 2-Aminomethyl and 3-Amino Pyrrolidines and Piperidines through 1,2-Diamination of Aldehydes

An efficient method for the synthesis of 1,2-diamines from aldehydes through proline-catalyzed asymmetric alpha-amination followed by reductive amination is reported. The products resemble those obtained through direct asymmetric diamination of terminal alkenes. The methodology is used to synthesize 2-aminomethyl and 3-amino pyrrolidines and piperidines in high yields and with a good enantioselectivity. The usefulness of the method is demonstrated through the synthesis of a 2-aminomethyl iminocyclitol.

Catalytic Asymmetric Aza-Diels-Alder Reaction: Pivotal Milestones and Recent Applications to Synthesis of Nitrogen-Containing Heterocycles

In this review, the pivotal achievements and recent advances in catalytic asymmetric aza-DAR reported up to 2020 are retrospectively considered and their potency for enantioselective synthesis of useful chiral piperidine, quinoline, pyridazine, oxazine and oxadiazine derivatives and fused compounds of higher molecular complexity bearing these pharmacology-relevant heterocyclic scaffolds is demonstrated. The reported data are systematized according both to key electron transfer modes (normal or invers electron demand reactions) and to main types of attainable heterocyclic products. Of significant attention are an analysis of activation strategies (complexation, enamine or enolate formation, H-bonding, etc.) applicable to reactions with particular types of dienes and dienophiles and identification of plausible reaction pathways (either concerted or stepwise) over stereoselective cyclization processes. The review contains 310 references and 122 synthetic schemes.

Second basic pKa: An overlooked parameter in predicting phospholipidosis-inducing potential of diamines

In this paper, we present the phospholipidosis-inducing potential (PLIP) of forty fragment-sized diamines derived from N-benzyl-4-(methylamino)piperidine and discuss the relationship between their PLIP and the physicochemical properties. Our results demonstrate that the previously reported methods are not suitable for predicting the PLIP of fragment-sized diamines; the second basic pKa can distinguish PLIP-positive diamines from PLIP-negative diamines more accurately than ClogP or most basic pKa. To the best of our knowledge, this is the first report describing the relationship between PLIP and second basic pKa.

An intramolecular, charge-assisted ammonium-N-H center dot center dot center dot O(hydroxyl) hydrogen bond ensures the hydroxy-O and ammonium-N atoms lie to the same side of the molecule [O-h-C-m-C-m-N-a (h = hydroxyl) = -59.7 (2)degrees]. In the crystal, charge-assisted hydroxyl-O-H center dot center dot center dot O- (carboxylate) and ammonium-N+-H center dot center dot center dot O-(carboxylate) hydrogen bonds generate a supramolecular chain along [010]; the chain is consolidated by C-H center dot center dot center dot O interactions. Links between chains to form supramolecular layers are of the type C-Cl center dot center dot center dot pi (quinolinyl-C-6) and the layers thus formed stack along the a-axis direction without directional interactions between them. The analysis of the calculated Hirshfeld surface points to the dominance of F center dot center dot center dot H contacts to the surface (40.8%) with significant contributions from F center dot center dot center dot F (10.5%) and C center dot center dot center dot F (7.0%) contacts.
