Rapid reduction of heteroaromatic nitro groups using catalytic transfer hydrogenation with microwave heating

A method for the rapid, safe reduction of heteroaromatic and aromatic nitro groups to amines is described using catalytic transfer hydrogenation under microwave heating conditions. Commonly available Pd/C or Pt/C catalyst is extremely effective with 1,4-cyclohexadiene as the hydrogen transfer source. In the case of substrates containing potentially labile aromatic halogens, Pt/C is effective and results in little or no dehalogenation. In general, the reactions are complete within 5 min at 120 C.

A NOVEL PROCESS FOR THE PREPARATION OF TERIFLUNOMIDE

The present invention provides a process for the preparation of Teriflunomide (Formula-I). The present invention describes the synthesis of Teriflunomide without isolating the intermediate Leflunomide. Teriflunomide is prepared from 5-Methyl isoxazole-4-carboxylic acid by converting to its acid chloride and coupling with 4-trifluoromethyl aniline to obtain Leflunomide (which is not isolated) followed by ring opening reaction using aq. Sodium Hydroxide to form Teriflunomide. In other words, the process is telescoped from 5- methylisoxazole-4-carbonyl chloride.

Synthesis of isochalcogenazole rings by treating beta-(N,N- dimethylcarbamoylchalcogenenyl)alkenyl ketones with hydroxylamine-O-sulfonic acid

beta-(N,N-Dimethylcarbamoylselenenyl)- and beta-(N,N- dimethylcarbamoyltellurenyl)alkenyl ketones were converted into isoselenazoles and isotellurazole Te-oxides, respectively, simply by treating with hydroxylamine-O-sulfonic acid, and deoxygenation of the latter products was successfully carried out by treating with PPh3. Alternative treatment of ynone oxime tosylates with hydrochalcogenide ions or N,N- dimethylchalcogenocarbamate ions also gave the same isochalcogenazole rings. These reactions were assumed to proceed through intramolecular nucleophilic substitution on the nitrogen atom of oxime sulfonates by the attack of in situ generated chalcogen nucleophiles.

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 1008-75-9 is helpful to your research. Related Products of 1008-75-9

Benzylamide antagonists of protease activated receptor 2 with anti-inflammatory activity

Activation of protease activated receptor 2 (PAR2) has been implicated in inflammatory and metabolic disorders and its inhibition may yield novel therapeutics. Here, we report a series of PAR2 antagonists based on C-terminal capping of 5-isoxazolyl-l-cyclohexylalanine-l-isoleucine, with benzylamine analogues being effective new PAR2 antagonists. 5-Isoxazolyl-l-cyclohexylalanine-l-isoleucine-2-methoxybenzylamine (10) inhibited PAR2-, but not PAR1-, induced release of Ca2+(IC500.5 muM) in human colon cells, IL-6 and TNFalpha secretion (IC501-5 muM) from human kidney cells, and was anti-inflammatory in acute rat paw inflammation (ED505 mg/kg sc). These findings show that new benzylamide antagonists of PAR2 have anti-inflammatory activity.

Reactivity in the Gas Phase. Behaviour of Isoxazoles under Negative Ion Chemical Ionization Conditions

– ions of isoxazole (1a), 3-methylisoxazole (1b), 5-methylisoxazole (1c), 5-phenylisoxazole (1d) and benzoylacetonitrile (2a) are generated using NICI/OH- or NICI/NH2- techniques.Their fragmentation pathways are rationalized on the basis of collision-induced dissociation and mass-analysed ion kinetic energy spectra and by deuterium labelling studies. 5-Substituted isoxazoles 1c and 1d, after selective deprotonation at position 3, mainly undergo N-O bond cleavage to the stable alpha-cyanoenolate NC-CH=CR-O- (R=Me, Ph) that fragments by loss of R-CN, or R-H, or H2O.The same alpha-cyanoenolate anion (R=Ph) is obtained from 2a with OH-, or NH2-, confirming the structure assigned to the – ion of 1d.On the contrary, 1b is deprotonated mainly at position 5 leading, via N-O and C(3)-C(4) bond cleavages, to H-C<*>-O- and CH3CN.Isoxazole (1a) undergoes deprotonation at either position and subsequent fragmentations.Deuterium labelling revealed an extensive exchange between the hydrogen atoms in the ortho position of the phenyl group and the deuterium atom in the alpha-cyanoenolate NC-CD=CPh-O-.
