Rhodium-catalyzed dynamic kinetic asymmetric transformations of racemic tertiary allylic trichloroacetimidates with anilines

The rhodium-catalyzed regio- and enantioselective amination of racemic tertiary allylic trichloroacetimidates with a variety of aniline nucleophiles is a direct and efficient route to chiral alpha,alpha-disubstituted allylic N-arylamines. We describe the first dynamic kinetic asymmetric transformations of racemic tertiary allylic electrophiles with anilines utilizing a chiral diene-ligated rhodium catalyst. The method allows for the formation of alpha,alpha-disubstituted allylic N-arylamines in moderate to good yields with good to excellent levels of regio- and enantioselectivity.

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.Recommanded Product: 5-(4-Hydroxyphenyl)isoxazole-3-carboxylic acid, you can also check out more blogs about33282-15-4

Access to Chiral 2,5-Pyrrolidinyl Dispirooxindoles via Dinuclear Zinc-Catalyzed Asymmetric Cascade Reactions

A series of new nonsymmetric semi-azacrown ether ligands were developed and applied to the asymmetric Michael/cyclic keto-imine formation/Friedel-Crafts alkylation reactions of 3-amino oxindole hydrochlorides and beta,gamma-unsaturated alpha-keto amides. A diversity of 2,5-pyrrolidinyl dispirooxindoles containing two nonadjacent spiro-quaternary stereocenters were obtained in excellent diastereoselectivities and moderate to excellent enantioselectivities (up to 95% ee). A possible catalytic cycle was proposed to explain the origin of the asymmetric induction.

Dust evolution, a global view: II. top-down branching, nanoparticle fragmentation and the mystery of the diffuse interstellar band carriers

The origin of the diffuse interstellar bands (DIBs), one of the longest-standing mysteries of the interstellar medium (ISM), is explored within the framework of The Heterogeneous dust Evolution Model for Interstellar Solids (THEMIS). The likely nature of the DIB carriers and their evolution is here explored within the framework of the structures and sub-structures inherent to doped hydrogenated amorphous carbon grains in the ISM. Based on the natural aromatic-rich moieties (asphaltenes) recovered fromcoal and oil, the likely structure of their interstellar analogues is investigated within the context of the diffuse band problem. It is here proposed that the top-down evolution of interstellar carbonaceous grains, and, in particular, a-C(:H) nanoparticles, is at the heart of the formation and evolution of the DIB carriers and their associations with small molecules and radicals, such as C2, C3, CH and CN. It is most probable that the DIBs are carried by dehydrogenated, ionized, hetero-cyclic, olefinic and aromatic-rich moieties that form an integral part of the contiguous structure of hetero-atomdoped hydrogenated amorphous carbon nanoparticles and their daughter fragmentation products.Within this framework, it is proposed that polyene structures in all their variants could be viable DIB carrier candidates.

Chiral Aryliodine-Mediated Enantioselective Organocatalytic Spirocyclization: Synthesis of Spirofurooxindoles via Cascade Oxidative C-O and C-C Bond Formation

An enantioselective organocatalytic oxidative spirocyclization of alkyl 3-oxopentanedioate monoamide derivatives leading to the formation of diverse spirofurooxindoles with high enantioselectivity has been realized via chiral aryliodine-mediated cascade C-O and C-C bond formations. The reaction is postulated to proceed via oxidative C-O bond formation followed by oxidative C-C bond formation, with the latter being the enantioselectivity-determining step.

Pharmacological Inhibition of Protein Tyrosine Phosphatase 1B: A Promising Strategy for the Treatment of Obesity and Type 2 Diabetes Mellitus

Obesity and metabolic syndrome represent major public health problems, and are the biggest preventable causes of death worldwide. Obesity is the leading risk factor for type 2 diabetes mellitus (T2DM), cardiovascular diseases and non-alcoholic fatty liver disease. Obesity-associated insulin resistance, which is characterized by reduced uptake and utilization of glucose in muscle, adipose and liver tissues, is a key predictor of metabolic syndrome and T2DM. With in-creasing prevalence of obesity in adults and children, the need to identify and characterize potential targets for treating metabolic syndrome is imminent. Emerging evidence from animal models, clinical studies and cell lines studies suggest that protein tyrosine phosphatase 1B (PTP1B), an enzyme that negatively regulates insulin signaling, is likely to be involved in the pathways leading to insulin resistance. PTP1B is tethered to the cytosolic surface of endoplasmic reticulum (ER), an organelle that is responsible for folding, modification, and trafficking of proteins. Recent evidence links the disruption of ER homeostasis, referred to as ER stress, to the pathogenesis of obesity and T2DM. PTP1B has been recognized as an important player linking ER stress and insulin resistance in obese subjects. This review highlights recent advances in the research related to the role of PTP1B in signal transduction processes implicated in pathophysiology of obesity and type 2 diabetes, and focuses on the potential therapeutic exploitation of PTP1B inhibitors for the management of these conditions.
