Three-Component Coupling of Aldehydes, 2-Aminopyridines, and Diazo Esters via Rhodium(III)-Catalyzed Imidoyl C-H Activation: Synthesis of Pyrido[1,2-a]pyrimidin-4-ones

Imines formed in situ from 2-aminopyridines and aldehydes undergo Rh(III)-catalyzed imidoyl C-H activation and coupling with diazo esters to give pyrido[1,2-a]pyrimidin-4-ones. Aromatic and enolizable aliphatic aldehydes were both effective substrates, and a broad range of functional groups were incorporated at different sites on the heterocyclic products. In addition, methoxy and dimethylamino functionalities could be directly installed on the pyrimidine ring by employing trimethyl orthoformate or N,N-dimethylformamide dimethyl acetal in place of the aldehyde, respectively.

AuCl3- and AuCl3-Phenylacetylene-Catalyzed Glycosylations by Using Glycosyl Trichloroacetimidates

Glycosylations of armed and disarmed trichloroacetimidate-based glycosyl donors were carried out by using the AuCl3-phenylacetylene relay catalyst system. The effectiveness of this catalytic system was also compared with that of using AuCl3 alone as a catalyst. Glycosylations with these catalysts proceeded efficiently at room temperature within 5-45 min. Excellent diastereoselectivity was obtained for the glycosylation of 2-O-acetyl-protected disarmed glycosyl donors, whereas armed glycosyl trichloroacetimidates gave rise to a mixture of anomeric glycosides. Acid-sensitive nucleophiles such as Fmoc-serine tert-butyl ester or Fmoc-threonine tert-butyl ester successfully underwent the glycosylations, albeit in moderate yields, under mild conditions at room temperature. We have reported a convenient room temperature protocol that employs AuCl3 and phenylacetylene as a catalyst system to carry out the glycosylation of glycosyl trichloroacetimidates. The effectiveness of this relay catalyst system was also compared with that of using AuCl3 alone to catalyze the glycosylations.

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.COA of Formula: C36H36Cl3NO6, you can also check out more blogs about74808-09-6

Synthesis and study of N-acetyl d-glucosamine triazole derivatives as effective low molecular weight gelators

Sugar based low molecular weight gelators have many potential uses for the formation of advanced soft materials. Here we have synthesized a series of peracetylated d-glucosamine triazole derivatives via the Cu catalyzed azide/alkyne cycloaddition reaction (CuAAc) and studied their self-assembling properties in several organic solvents, aqueous solutions, and water. Among the sixteen compounds synthesized and studied, many were able to function as organogelators for multiple solvents. Also seven compounds were able to form hydrogels at low concentrations such as 0.2-1.0 wt %. These indicate that peracetylated d-glucosamine triazole analogs are effective small molecular gelators.

Self-assembly of molecules containing the 2-aminopyridine unit in non-polar solvents

A combined experimental and theoretical study on the self-assembly of three molecules, 2,2?-dipyridylamine, 2-(1-phenylamino)pyridine and 2-methylaminopyridine was performed. The effect of concentration increase in low-polarity solvents was investigated. The average molecular weights, dipole moments and IR spectra of these compounds were measured in C6H 6, CCl4 and CHCl3. A strong association of all these molecules was found, through N-H…N hydrogen bonding. The form of associates is different; in molecules containing the N-aromatic ring the aggregates have a dipole moment decreasing with concentration whereas in N-methylaminopyridine a considerable increase in dipole moment with concentration was observed. DFT B3LYP/6-31G(d,p) calculations for monomers, dimers, trimers and tetramers of these three molecules were performed to model the structures of possible aggregates. Copyright

LC-MS/MS method for quantification of atorvastatin, o-hydroxyatorvastatin, p-hydroxyatorvastatin, and atorvastatin lactone in rat plasma

A simple and sensitive liquid chromatography-tandem mass spectrometry method was developed for the quantification of atorvastatin, ortho-hydroxyatorvastatin, para-hydroxyatorvastatin, and atorvastatin lactone in rat plasma. Solid-phase extraction was used for preparation of samples. Rosuvastatin was chosen as an internal standard. Chromatographic separation was achieved on ZORBAX Eclipse C18 Analytical, 4.6 ¡Á 100 mm (3.5 mum) column with a gradient mobile phase composed of acetonitrile and 0.1% acetic acid, at a flow rate of 400 muL min-1. The column was kept at constant temperature (25 C), and autosampler tray temperature was set at 4 C. The following selected reaction monitoring (SRM) transitions were selected: (m/z, Q1 ? Q3, collision energy) atorvastatin (559.47 ? 440.03, 22 eV), atorvastatin lactone (541.36 ? 448.02, 19 eV), orthohydroxyatorvastatin (575.20 ? 440.18, 20 eV), para-hydroxyatorvastatin (575.54 ? 440.18, 20 eV), and rosuvastatin (482.25 with selected combination of two fragments 257.77, 31 eV, and 299.81, 35 eV) in positive ion mode. The method was validated over a concentration range of 0.5-20 ng mL-1 for ortho-hydroxyatorvastatin and para-hydroxyatorvastatin and 0.1-20 ng mL-1 for atorvastatin and atorvastatin lactone with excellent linearity (r2 = 0.99). This method demonstrated acceptable precision and accuracy at four quality control concentration levels. The detection limits were 0.1 and 0.13 ng mL-1 for orthohydroxyatorvastatin and para-hydroxyatorvastatin, respectively, and 0.05 ng mL-1 for atorvastatin and atorvastatin lactone. All analytes were found to be stable at examined conditions. Validated method was applied for determination of atorvastatin and its metabolites in plasma of experimental animals.

Scalable synthesis of a nonracemic alpha-arylpropionic acid via ketene desymmetrization for a glucokinase activator

Process research and development for a synthesis of the chiral carboxylic acid (R)-2 as a key intermediate of the glucokinase activator (R)-1 is described. The construction of the stereocenter at the alpha-carbon is a key point for the synthesis of (R)-2. The proposed process utilizes desymmetrization of a ketene in situ generated from the corresponding racemic carboxylic acid Rac-2 with (R)-pantolactone as a chiral auxiliary followed by hydrolysis of the resulting ester. This key step has been successfully scaled up to 20 kg, which demonstrates that this synthetic approach is comparable with a previously reported approach via enantioselective hydrogenation.

Biphasic hydrogenation of olefins by functionalized ionic liquid-stabilized palladium nanoparticles

Palladium nanoparticles in the size range of 5-6 nm were prepared conveniently by reducing palladium(II) with atmospheric pressure hydrogen and stabilized by 2,2?-dipyridylamine-functionalized imidazolium cations according to our approach. The efficient catalytic conversion of cyclohexene into cyclohexane by the functionalized ionic liquid-stabilized palladium nanoparticles has been performed under very mild hydrogen pressure (0.1 MPa) and at 35C. It was found that the concentration of palladium and the reaction temperature considerably affected the size and degree of aggregation of Pd nanoparticles in ionic liquid, which further changed the performance of the catalyst activity. The synthesized nanocatalysts can be recycled at least five times without any loss of the activity. Finally, the scope of substrates was also investigated. The excellent catalytic activity of the present system can be attributed to good stabilization and high dispersion of palladium nanoparticles.
