Iridium(III)-Catalyzed C?H Amidation of Arylphosphoryls Leading to a P-Stereogenic Center

Direct C?H amidation of arylphosphoryl compounds has been developed by using an IrIIIcatalyst system under mild conditions. A wide range of substrates could be employed with high functional-group tolerance. This procedure was successfully applied for the first time to the asymmetric reaction giving rise to a P-chirogenic center with a high diastereomeric ratio of up to 19:1 (90 % de).

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 49676-42-8 is helpful to your research., Electric Literature of 49676-42-8

Preparation of new sulfonated triarylphosphanes: Control of the selectivity by structural assistance

A synthetic approach for the selective preparation of tri-, di-, and monosulfonated triarylphosphanes is presented. PPhnAr3-n parent phosphanes (1a-8a) having aryl rings (Ar) activated by simple electron donating groups (CH3, CH3O) were prepared by the standard Grignard method. The activated rings could be sulfonated selectively under mild conditions and with short reaction times (0.8-3 h). Using a very simple workup procedure, the corresponding tri-, di-, and monosulfonated phosphanes (1b-8b) were isolated in outstanding yields (88-99%) and found to contain negligible amount of phosphane oxides (0-4%).

Anodic Bahavior of Crowded Triarylphosphines. ESR Study of Triarylphosphoniumyl Radicals, Ar3P.+

A large number of triarylphosphines exhibiting different steric hindrance has been prepared.The pyramidalization angle alpha of these compounds was calculated with use of the MM2 force field and was shown to depend almost exclusively on the number of ortho substituents on the phenyl rings.In a series of isosteric (same alpha) phosphines, the oxidation potential correlates with the sum of the ?+ Hammett parameters of the phenyl substituents.In the absence of oxygen, anodic oxidation of all the triarylphosphines bearing two o-methyl substituents on each phenyl ring is reversible and yields very persistent phosphoniumyl radicals.These radicals are easly detected by ESR in liquid solution and were shown to retain a pyramidal geometry that is significantly flattened compared to that of the parent phosphine.

Discovery of a Potent and Selective Oral Inhibitor of ERK1/2 (AZD0364) That Is Efficacious in Both Monotherapy and Combination Therapy in Models of Nonsmall Cell Lung Cancer (NSCLC)

The RAS/MAPK pathway is a major driver of oncogenesis and is dysregulated in approximately 30% of human cancers, primarily by mutations in the BRAF or RAS genes. The extracellular-signal-regulated kinases (ERK1 and ERK2) serve as central nodes within this pathway. The feasibility of targeting the RAS/MAPK pathway has been demonstrated by the clinical responses observed through the use of BRAF and MEK inhibitors in BRAF V600E/K metastatic melanoma; however, resistance frequently develops. Importantly, ERK1/2 inhibition may have clinical utility in overcoming acquired resistance to RAF and MEK inhibitors, where RAS/MAPK pathway reactivation has occurred, such as relapsed BRAF V600E/K melanoma. We describe our structure-based design approach leading to the discovery of AZD0364, a potent and selective inhibitor of ERK1 and ERK2. AZD0364 exhibits high cellular potency (IC50 = 6 nM) as well as excellent physicochemical and absorption, distribution, metabolism, and excretion (ADME) properties and has demonstrated encouraging antitumor activity in preclinical models.

Sterically demanding, zwitterionic trialkylphosphonium sulfonates as air-stable ligand precursors for efficient palladium-catalyzed cross-couplings of aryl bromides and chlorides

3-(Di-tert-butylphosphonium)propane sulfonate (DTB-PPS) and 3-(diadamantylphosphonium)propane sulfonate (DAPPS) are air-stable pre-ligands for aqueous-phase palladium-catalyzed cross-coupling reactions. Both DTBPPS and DAPPS were found to give active catalysts for the Sonogashira coupling of aryl bromides at room temperature and 4-chloroanisole at 80 C. These ligands also gave effective catalysts for the aqueous-phase Suzuki coupling of aryl bromides at room temperature.
