Synthesis of versatile nonsymmetric amine- and boron-functionalized troeger’s base derivatives, including a troeger’s base amino acid

Troeger’s base is a building block with a unique rigidity and geometry that has an increasing number of applications in a variety of nanoscale chemistry projects. This paper describes the facile synthesis of a set of Troeger’s base derivatives that have lost their C2 symmetry by virtue of having each ring differentiated, and contain amine, carboxylate, halogen, and/or boronate substituents to enable a large number of different cross-coupling and amide coupling reactions. We also describe the synthesis and preliminary chiral resolution of a new Troeger’s base amino acid building block. Novel, nonsymmetric Troeger’s base compounds have been synthesized that are convenient starting points for further elaboration by cross-coupling and amide coupling reactions. Examples include the preparation of a novel Troeger’s base amino acid. Copyright

Palladium-Catalyzed Cascade Cyclization of Alkene-Tethered Aryl Halides with o-Bromobenzoic Acids: Access to Diverse Fused Indolo[2,1- A[isoquinolines

A novel palladium-catalyzed cascade cyclization of alkene-tethered aryl halides with o-bromobenzoic acids is described, which provides an efficient avenue for building various fused hexacyclic scaffolds containing indolo[2,1-a]isoquinoline in moderate to excellent yield. The method enables the construction of three C-C bonds through an intramolecular carbopalladation, C-H activation, and a decarboxylation sequence. Furthermore, dihydrocyclohepta[de]naphthalene-fused indolo[2,1-a]isoquinolines can be synthesized in moderate yield by constructing a seven-membered ring.

Design of cationic conjugated polyelectrolytes for DNA concentration determination

Cationic conjugated polyelectrolytes poly110 and poly1 20 were designed, synthesized, and characterized with the anticipation of function in the determination of double-stranded DNA concentration [dsDNA]. Their structures contain a pi-delocalized optically active backbone composed of phenylene-fluorene segments copolymerized with 2,1,3-benzothiadiazole (BT) units and charged pendant groups that allow excellent solubility in water. The subscript in poly1x refers to the molar percent of BT units in the chain. Addition of dsDNA to poly110 or poly120 results in a change in the color of emission from blue to green. These spectral changes can be treated to obtain the parameter delta, which can be used to generate calibration curves that indicate [dsDNA]. Analysis of photoluminescence spectra reveals that dsDNA addition gives rise to more efficient FRET from blue emitting segments to the BT sites, an increase in the BT emission quantum yield, and partial quenching of the phenylene-fluorene segments. Studies were also carried out to maximize the range of [dsDNA] determination. We find that by combining the response from two different initial concentrations of poly110, it is possible to generate calibration curves that respond with a difference in [dsDNA] of over 7 orders of magnitude.

Paracyclophane-based monophosphine ligand for palladium-catalyzed cross-coupling reactions of aryl chlorides

A new [2.2]paracyclophane-based electron-rich and sterically bulky monophosphine ligand has been synthesized by an efficient and straightforward method. When combined with palladium, this ligand shows excellent performance in the Buchwald-Hartwig amination and Suzuki-Miyaura coupling reactions of various aryl chlorides. In both types of reactions, ortho-substituted, deactivated aryl chlorides are shown to be viable substrates. However, the Suzuki-Miyaura coupling appears to be easier, with palladium loading at 0.1 mol% being feasible. The Royal Society of Chemistry 2009.

Total synthesis of kendomycin: A macro-C-glycosidation approach

Kendomycin, also known as (-)-TAN 2162, is a novel polyketide-derived ansamycin isolated from Streptomyces sp., which exhibits potent antagonist and agonist activities at the endothelin and calcitonin receptors, respectively. This bacterial metabolite also possesses a strong antibiotic activity against a range of gram-positive and -negative bacteria and cytostatic effects on the growth of human cancer cell lines. When a novel macroglycosidation reaction is employed as the key step, the first enantioselective total synthesis of kendomycin has been accomplished. A Friedel-Crafts-type ring closure of the acyclic precursor containing tetrahydropyran and benzofuran moieties produces the macrocycle as a single stereoisomer in good yield, thus establishing the aryl C-glycosidic linkage of the ansa core. This reaction requires a phenolic glycosyl acceptor and appears to proceed through a rapid O-glycosidation followed by a slow rearrangement to an aryl C-glycoside. The requisite secomacrocycle is prepared by the Pd(0)-catalyzed B-alkyl Suzuki-Miyaura cross-coupling of two subunits, which in turn can be expeditiously assembled from readily available building blocks in a modular fashion.

Synthesis, structural characterization, and unusual field-effect behavior of organic transistor semiconductor oligomers: Inferiority of oxadiazole compared with other electron-withdrawing subunits

A new series of heterocyclic oligomers based on the 1,3,4-oxadiazole ring were synthesized. Other electron-deficient cores (fluorenone and fumaronitrile) were introduced to investigate the oligomers as n-channel materials. The physical properties, thin film morphologies, and field-effecttransistor characteristics of the oligomers were evaluated. Thin films were deposited at different substrate temperatures and on variously coat ed Si/Si02 for device optimization. Contrary to our expectations, the thin film devices of 4 revealed p-channel behavior, and the average hole mobility was 0.14 cm 2 V-1 s-1 (maximum value 0.18 cm2 V-1 s-1). Compound 11 is the first example of an oxadiazole-containing organic semiconductor (OSC) oligomer in an n-channel organic field-effect transistor (OFET) and shows moderate mobilities. Non- oxadiazole-containing oligomers 9 and 12 showed n-channel OFET behavior on hexamethyldisilazane- treated and Cytop spin-coated Si02 in vacuum. These are the first fluorenone- and fumaronitrile-based n-OSCs demonstrated in transistors. However, oxadiazole-core materials 14 and 16 were inactive in transistordevices.

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.SDS of cas: 95464-05-4, you can also check out more blogs about95464-05-4

Microwave-assisted suzuki coupling reaction for rapid synthesis of conjugated polymer-poly(9,9-dihexylfluorene)s as an example

Long reaction period (dozens of hours) is often required for the synthesis of conjugated polymers by palladium-catalyzed Suzuki polymerization reaction. This work shows that microwave can accelerate Suzuki polymerization to realize the ultra-rapid synthesis of conjugated polymers, here poly(9,9-dihexylfluorene) s (PDHFs) as an example. The effects of reaction conditions on the polymerization have been systematically investigated, including the mode of microwave irradiation, microwave power, reaction temperature, reaction time, solvents, catalyst species, and catalyst concentrations. Compared with the conventional heating method (oil bath) for the synthesis of PDHFs (48 h, M w = 20,000 g/mol), Suzuki polymerization under optimized microwave condition can yield PDHFs with higher molecular weight (Mw = 40,000 g/mol) in a much shorter time (14 min). The structures of obtained PDHFs samples are fully characterized spectroscopically, demonstrating well-defined PDHFs have been prepared through microwave-assisted (MA) Suzuki polymerization reaction. In addition, the mechanism of MA Suzuki polymerization is proposed preliminarily. 2013 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2013 Microwave-assisted (MA) Suzuki polymerization for polyfluorenes has been systematically investigated. It is very important to control the reaction conditions in order to depress the formation of cross-linked products. Compared with oil bath heating, MA synthesis can greatly reduce the reaction time from 48 h (oil bath heating) to 14 min, and resultant polymer products show the higher molecular weight of 40,000 under optimized conditions.
