Quinuclidine Stabilized on FeNi3 Nanoparticles as Catalysts for Efficient, Green, and One-Pot Synthesis of Triazolo[1,2-a]indazole-triones

A new magnetically separable catalyst consisting of quinuclidin-3-thiol supported on propylsilane-functionalized silica-coated FeNi3 nanoparticles (FeNi3/quinuclidine) has been prepared. The synthesized catalyst was characterized by powder X-ray diffraction, transmission electron microscopy, vibrating sample magnetometry, thermogravimetric analysis, and Fourier transform infrared spectroscopy. The immobilized FeNi3/quinuclidine was shown to be an efficient heterogeneous catalyst for the synthesis of triazolo[1,2-a]indazole-triones under solvent-free conditions at room temperature. The catalyst is readily recovered by simple magnetic decantation and can be recycled several times with no significant loss of catalytic activity.

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 1120-28-1, in my other articles.

Stereospecific formation of polycyclic ferrocenyldihydropyrazoles based on Z- and E-isomeric ferrocenyl- substituted alpha,beta-unsaturated ketones of the heterocyclic series

The reactions of E- and Z-isomeric 2-(ferrocenylmethylidene)quinuclidin-3-one, 1-methyl-3-(ferrocenylmethylidene)piperidin-4-one, and 2-(ferrocenylmethylidene)tropinone with hydrazine proceed stereospecifically to form the same diastereomeric polycyclic ferrocenyldihydropyrazoles regardless of the geometrical configuration of the starting alpha,beta -unsaturated ketones. The structure of the trans-diastereomer of 4-acetyl-3-ferrocenyl-1,4,5-triazatricyclo[5.2.2.0(2,6)]undec-5-ene was established by X-ray diffraction analysis.

3-HETEROARYL-SUBSTITUTED QUINUCLIDIN-3-OL AND QUINUCLIDIN-2-ENE DERIVATIVES AS MUSCARINIC ANTAGONISTS – SYNTHESIS AND STRUCTURE-ACTIVITY-RELATIONSHIPS

A number of 3-heteroaryl-substituted quinuclidin-3-ol and quinuclidin-2-ene derivatives have been prepared and evaluated for muscarinic and antimuscarinic properties. The affinities of the new compounds (13, 14, 16-32, and 36-52a,b) were tested in homogenates of cerebral cortex, heart, parotid gland, and urinary bladder from guinea pigs using (-)-[H-3]-3-quinuclidinyl benzilate [(-)-[H-3]QNB] as the radioligand and in a functional assay using isolated guinea pig urinary bladder. The present compounds behaved as competitive muscarinic antagonists in the urinary bladder. The highest receptor binding affinity, K-i (cortex) = 9.6 nM, was observed for 3-(2-benzofuranyl)quinuclidin-2-ene (31). The corresponding 3-benzofuranyl (36) and 3-benzothienyl (37) homologues had about 3.5-fold lower affinity for cortical muscarinic receptors. All quinuclidin-3-ol derivatives (14 and 16-25) had lower binding affinities for the different muscarinic receptor subtypes than the corresponding quinuclidin-2-ene analogues when examined in the various tissue homogenates. In general, the new compounds showed low subtype selectivity. The structure-affinity relationships are discussed in terms of differences in proton basicity of the azabicyclic nitrogen and differences in geometric, conformational, and/or electronic properties of the compounds. The cortical antimuscarinic potency is also related to the complementarity of the compounds to the putative binding site of the muscarinic mi receptor.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 112-86-7 is helpful to your research. Recommanded Product: 112-86-7.

Evaluation of (Z)-2-((1-benzyl-1H-indol-3-yl)methylene)-quinuclidin-3-one analogues as novel, high affinity ligands for CB1 and CB2 cannabinoid receptors

A small library of N-benzyl indolequinuclidinone (IQD) analogs has been identified as a novel class of cannabinoid ligands. The affinity and selectivity of these IQDs for the two established cannabinoid receptor subtypes, CB1 and CB2, was evaluated. Compounds 8 (R = R-2 = H, R-1 = F) and 13 (R = COOCH3, R-1 = R-2 = H) exhibited high affinity for CB2 receptors with K-i values of 1.33 and 2.50 nM, respectively, and had lower affinities for the CBI receptor (K-i values of 9.23 and 85.7 nM, respectively). Compound 13 had the highest selectivity of all the compounds examined, and represents a potent cannabinoid ligand with 34-times greater selectivity for CB2R over CB1R. These findings are significant for future drug development, given recent reports demonstrating beneficial use of cannabinoid ligands in a wide variety of human disease states including drug abuse, depression, schizophrenia, inflammation, chronic pain, obesity, osteoporosis and cancer.
