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.

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 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.

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.

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.

Synthesis, characterization and evaluation of novel benzothiazole clubbed chromene derivatives for their anti-inflammatory potential

A series of chromene derivatives (5a-f) were prepared by multistep synthesis process using 2-[3-phenyl prop-2-ene nitrile] 1,3-benzothiazole and dimedone using piperidine as catalyst in ethanol. The reaction was found to proceed via Knoevenagel condensation of aldehydes with benzothiazole, followed by the elimination to afford the 2-(benzo[d]thiazol-2-yl)-3-(aryl)acrylonitrile, which then undergoes Michael addition with 5,5-dimethyl-1,3-cyclohexanedione, followed by intramolecular O-cyclization to give the products. The structures of all novel constructed derivatives were corroborated by elemental analysis and spectral data (FT-IR, H-1-NMR, C-13-NMR and Mass). Subsequently, the compounds were tested for their in-vivo anti-inflammatory activity. This study revealed that these synthesized derivatives tend to have significantly anti inflammatory activity and shall prove as structural templates in the design and development of new anti inflammatory drugs.

Nonacidic Chemotype Possessing N-Acylated Piperidine Moiety as Potent Farnesoid X Receptor (FXR) Antagonists

Famesoid X receptor (FXR) plays a major role in the control of cholesterol metabolism. Antagonizing transcriptional activity of FXR is an effective means to treat the relevant metabolic syndrome. Some of antagonists so far have the charged functions; however, they may negatively affect the pharmacokinetics. We describe herein a structure activity relationship (SAR) exploration of nonacidic FXR antagonist 6 focusing on two regions in the structure and biological evaluation of nonacidic 10 with the characteristic N-acylated piperidine group obtained from SAR studies. As the robust affinity to FXR is feasible with our nonacidic analogue, 10 is among the most promising candidates for in vivo testing.

Microwave-Assisted Three-Component Domino Synthesis of Polysubstituted 4H-Pyran Derivatives and Their Anticancer Activity

An efficient microwave-assisted one-pot procedure has been proposed for the synthesis of new 4-aryl-6-(methylamino)-5-nitro-2-(1H-pyrrol-2-yl)-4H-pyran-3-carbonitriles by condensation of 3-oxo-3-(1H-pyrrol-2-yl)propanenitrile with (E)-N-methyl-1-(methylsulfanyl)-2-nitroethenamine and substituted benzaldehydes in the presence of a catalytic amount of piperidine using ethanol as a solvent. The transformation occurs via successive Knoevenagel condensation, Michael addition, and intramolecular cyclization. The proposed procedure is advantageous due to its one-pot mode, short reaction time, simple purification by recrystallization, and excellent yields. The product structure was confirmed using various spectroscopic techniques, including IR,H-1 and C-13 NMR, LC/MS, elemental analysis, and single crystal X-ray diffraction study. The synthesized compounds were evaluated for their anticancer activity against 60 different human cancer cell lines in nine cancer panels, and two compounds were found to be potent against different cell lines.
