Bipolar host materials for green triplet emitter in organic light-emitting diodes

We have developed novel bipolar host materials for high efficiency green phosphorescent OLEDs (PHOLEDs). Phenyl moieties were inserted in a 9,9?-(biphenyl-4,4?-diyl)dicarbazole (CBP) compound to provide much easier electron injection and to increase electron mobility. The efficiency increase and voltage reduction by this modification were observed in green PHOLEDs. At a given constant luminance of 1000 cd/m2, the power efficiency was enhanced about twenty percent in the general green PHOLED devices. Copyright

Synthesis, metal complex formation, and switching properties of spiropyrans linked to chelating sites

The synthesis of 5-pinacolato-2,2?-bipyridine and its applicability in cross-coupling reactions is reported. The use of this framework in Suzuki type cross-coupling reactions, together with a recently published way to achieve indolization has been used to synthesize new spiropyran systems attached to two bipyridine moieties. The indolization method followed, is based on an ‘in situ’ hydrolysis/Fischer cyclization protocol reported by Buchwald and co-workers. The synthesis of a new phenanthroline based spirooxazine attached to a bipyridine moiety is also reported. One of the spiropyran system was used as a ligand to form a ruthenium metal complex. There photophysical properties were tested with respect to the application as sensitizer in functionalized, wire-type bridging ligands in heteronuclear metal complexes.

(Chemical Equation Presented) Blocking the way: Substitution at the 2-position in pyridines and other N-heterocycles blocks N-coordination to an Ir center. This steric hindrance provides a substrate-design criterion that allows the Ir-catalyzed borylation of C-H bonds, which can be followed by Suzuki-Miyaura cross-coupling in a one-pot reaction (see scheme; B 2pin2 = bis(pinacolato-O,O?)diboron, dtbpy = 4,4?-tBu2-2,2?-bipyridine).

Insertion of Pt into C-H and C-S bonds of thiophene derivatives. The X-ray crystal structure of a thiaplatinacycle of 3,6-dimethylthieno [3,2-b]thiophene

Treatment of the zerovalent platinum complex [Pt(PEt3) 4] with 3,6-dimethylthieno[3,2-b]thiophene leads to a six-membered, approximately planar thiaplatinacycle, which has been characterised spectroscopically and by a single crystal X-ray determination. The reaction of [Pt(PEt3)4] with 2,2?-bithiophene and 1-methyl-2-(2-thienyl)pyrrole produced two types of products, thiaplatinacycles resulting from C-S insertion and platinum(II) hydrides arising from C-H insertion. These complexes were characterised spectroscopically.

A Conformational Restriction Strategy for the Identification of a Highly Selective Pyrimido-pyrrolo-oxazine mTOR Inhibitor

The mechanistic target of rapamycin (mTOR) plays a pivotal role in growth and tumor progression and is an attractive target for cancer treatment. ATP-competitive mTOR kinase inhibitors (TORKi) have the potential to overcome limitations of rapamycin derivatives in a wide range of malignancies. Herein, we exploit a conformational restriction approach to explore a novel chemical space for the generation of TORKi. Structure-activity relationship (SAR) studies led to the identification of compound 12b with a ?450-fold selectivity for mTOR over class I PI3K isoforms. Pharmacokinetic studies in male Sprague Dawley rats highlighted a good exposure after oral dosing and a minimum brain penetration. CYP450 reactive phenotyping pointed out the high metabolic stability of 12b. These results identify the tricyclic pyrimido-pyrrolo-oxazine moiety as a novel scaffold for the development of highly selective mTOR inhibitors for cancer treatment.

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 95464-05-4 is helpful to your research. Reference of 95464-05-4

Asymmetric crotylation reactions in synthesis of polypropionate-derived macrolides: Application to total synthesis of oleandolide

Complete details of a convergent asymmetric synthesis of oleandolide (1), the aglycon of the macrolide antibiotic oleandomycin, is described. The synthesis has been achieved through the assembly and coupling of the left- and right-hand subunits 12 and 38, respectively. These subunits were prepared from chiral silane-based asymmetric crotylation reactions to control the stereochemical relationships. The left- and right-hand subunits (C1-C7 and C8-C14) were brought together through a Pd(0)-catalyzed sp3-sp2 cross-coupling reaction between the zinc intermediate 40 and vinyl triflate 38 to give 27. This product was converted to seco acid 42a and cyclized to lactone 35 under Yamaguchi conditions. This material was then epoxidized with m-chloroperbenzoic acid (m-CPBA) to install the correct C8 epoxide as a single diastereomer, which after a short deprotection sequence completed the synthesis of oleandolide.
