Iron-Mediated Electrophilic Amination of Organozinc Halides using Organic Azides

A wide range of alkyl-, aryl- and heteroarylzinc halides were aminated with highly functionalized alkyl, aryl, and heterocyclic azides. The reaction proceeds smoothly at 50 C within 1 h in the presence of FeCl3 (0.5 equiv) to furnish the corresponding secondary amines in good yields. This method was extended to peptidic azides and provided the arylated substrates with full retention of configuration. To demonstrate the utility of this reaction, we prepared two amine derivatives of pharmaceutical relevance using this iron-mediated electrophilic amination as the key step.

Substituent Effects in Non-Aromatic Nitrogen Heterocycles: Alkaline Hydrolysis of Methyl N-Methyl(oxo)dihydropyridinecarboxylates and Diaza Analogues

Ester hydrolysis studies on some isomeric methoxycarbonyl derivatives of N-methylpyridin-2- and 4-ones show that reaction rates are affected by the relative positions of CO2Me, =O and NMe functions in ways which could not be predicted.However, from limited results for analogous pyrimidine derivatives, it seems that reactivity in these polyfunctional compounds can be predicted from the pyridine data by assuming additivity of effects.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C5H5ClN2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1121-79-5, Name is 3-Chloro-6-methylpyridazine, molecular formula is C5H5ClN2

Identification, synthesis, and biological evaluation of 6-[(6 R)-2-(4-fluorophenyl)-6-(hydroxymethyl)-4,5,6,7-tetrahydropyrazolo[1,5-a ]pyrimidin-3-yl]-2-(2-methylphenyl)pyridazin-3(2 H)-one (AS1940477), a potent p38 MAP kinase inhibitor

Several p38 MAPK inhibitors have been shown to effectively block the production of cytokines such as IL-1beta, TNFalpha, and IL-6. Inhibitors of p38 MAP kinase therefore have significant therapeutic potential for the treatment of autoimmune disease. Compound 2a was identified as a potent TNFalpha production inhibitor in vitro but suffered from poor oral bioavailability. Structural modification of 2a led to the discovery of tetrahydropyrazolopyrimidine derivatives, exemplified by compound 3, with an improved pharmacokinetic profile. We found that blocking metabolism at the methyl group of the amine and constructing the tetrahydropyrimidine core were important to obtaining compounds with good biological profiles and oral bioavailability. Pursuing the structure-activity relationships of this series led to the discovery of AS1940477 (3f), with excellent cellular activity and a favorable pharmacokinetic profile. This compound represents a highly potent inhibitor of p38 MAP kinase with regard to in vivo activity in an adjuvant-induced arthritis model.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C5H5ClN2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1121-79-5, in my other articles.

Process for dyeing mixed anionic/cationic polyamide substrates with a specific type of vinyl sulfone dye

The invention is a process for dyeing polyamide substrates comprising anionic and cationic fibers in multi-colored patterns. Cross-staining or dyeing of the cationic fibers by the anionic-dyeable nylon colorant is avoided. The anionic dyeable fiber portion is dyed with a fiber-reactive vinyl sulfone dye having one or more sulfonic acid substituents and one or more vinyl sulfone groups with the proviso that the sum of the number of sulfonic acid and vinyl sulfone substituents is at least three. The dyeing process is conducted at a pH of about 2 to about 4. Optionally the cationic portion of the substrate may be dyed with a basic dye in admixture with the vinyl sulfone dye.
