Ruthenium-catalyzed intramolecular cyclization of diazo-beta-ketoanilides for the synthesis of 3-alkylideneoxindoles

With [Ru(p-cymene)Cl2]2 as catalyst, diazo-beta-ketoanilides would undergo intramolecular carbenoid arene C-H bond functionalization to afford 3-alkylideneoxindoles in up to 92% yields. The reaction occurs under mild conditions and exhibits excellent chemoselectivity. The lack of primary KIE (kH/kD ? 1) suggests that the reaction should not proceed by rate-limiting C-H bond cleavage; a mechanism involving cyclopropanation of the arene is proposed.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 33282-15-4

The influence of alkyl substituents on the chromatographic indicator of self-association of N-containing heterocyclic compounds

The chromatographic indicator of the ability of substances to form associates in a pure liquid deltaTaub.p. proposed in our previous study was used to estimate the capacity for self-association of alkyl-substituted imidazoles, pyrazoles, pyrroles, oxazoles, isoxazoles, pyridazines, pyrimidines, pyrazines, and pyridines. Alkyl substituents introduced in heterocyclic compounds decrease the deltaTaub.p. values, which is consistent with the data on the heats of self-association of heterocyclic compounds in pure liquids. The reasons for the difference between the boiling point of a compound at standard pressure and its “gas-chromatographic boiling point” are discussed.

A Class of Amide Ligands Enable Cu-Catalyzed Coupling of (Hetero)aryl Halides with Sulfinic Acid Salts under Mild Conditions

The amide derived from 4-hydroxy-l-proline and 2,6-dimethylaniline is a powerful ligand for Cu-catalyzed coupling of (hetero)aryl halides with sulfinic acid salts, allowing the formation of a wide range of (hetero)aryl sulfones from the corresponding (hetero)aryl halides at considerably low catalytic loadings. The coupling of (hetero)aryl iodides and sodium methanesulfinate proceeds at room temperature with only 0.5 mol % CuI and ligand, representing the first example for Cu-catalyzed arylation at both low catalytic loading and room temperature.

Amidate Complexes of Tantalum and Niobium for the Hydroaminoalkylation of Unactivated Alkenes

A series of mono(amidate) Ta and Nb complexes with varying steric and electronic properties were synthesized. These complexes were screened as precatalysts for the hydroaminoalkylation of alkenes with secondary amines. Sterically demanding mono(amidate) Ta complexes were determined to be the most effective precatalysts. Isotopic labeling and kinetic studies were undertaken in an effort to elucidate the mechanism. The reaction was shown to be dependent upon catalyst and alkene concentration while being zero order in amine concentration. Mechanistic probes for radical species support a two-electron mechanism. Bis(amidate) species of Ta and Nb were also synthesized, with metallaaziridine formation observed for both metals. Insertion of acetonitrile into the reactive M-C bond yielded a representative five-membered metallacycle. Off-cycle equilibria and catalyst dormant states have been identified as areas for future catalyst development efforts.

Ligand-free Iron(II)-Catalyzed N-Alkylation of Hindered Secondary Arylamines with Non-activated Secondary and Primary Alcohols via a Carbocationic Pathway

Secondary benzylic alcohols represent a challenging class of substrates for N-alkylation of amines. Herein, we describe an iron(II)-catalyzed eco-friendly protocol for N-alkylation of secondary arylamines with secondary benzyl alcohols through a carbocationic pathway instead of the known borrowing hydrogen transfer (BHT) approach. Transiently generated carbocations, produced from alcohols via self-condensation, were coupled with arylamines to provide highly functionalized amine products. The scope of this methodology involves N-alkylation of primary, secondary and heterocyclic amines with primary/secondary benzylic, allylic and heterocyclic alcohols, which are common key structures in numerous pharmaceuticals drugs. The method can also be easily adopted for the amination of various natural products. (Figure presented.).

Re-education begins at home: an overview of the discovery of in vivo-active small molecule modulators of endogenous stem cells

Introduction: Degenerative diseases, such as Alzheimer?s disease, heart disease and arthritis cause great suffering and are major socioeconomic burdens. An attractive treatment approach is stem cell transplantation to regenerate damaged or destroyed tissues. However, this can be problematic. For example, donor cells may not functionally integrate into the host tissue. An alternative methodology is to deliver bioactive agents, such as small molecules, directly into the diseased tissue to enhance the regenerative potential of endogenous stem cells. Areas covered: In this review, the authors discuss the necessity of developing these small molecules to treat degenerative diseases and survey progress in their application as therapeutics. They describe both the successes and caveats of developing small molecules that target endogenous stem cells to induce tissue regeneration. This article is based on literature searches which encompass databases for biomedical research and clinical trials. These small molecules are also categorized per their target disease and mechanism of action. Expert opinion: The development of small molecules targeting endogenous stem cells is a high-profile research area. Some compounds have made the successful transition to the clinic. Novel approaches, such as modulating the stem cell niche or targeted delivery to disease sites, should increase the likelihood of future successes in this field.
