Generation and Characterization of Four Dilutions of Diesel Engine Exhaust fo...
Exposure atmospheres for a rodent inhalation toxicology study were generated from the exhaust of a 2000 Cummins ISB 5.9L diesel engine coupled to a dynamometer and operated on a... -
Dendrimer-Supported Oligothiophene Synthesis: Aliphatic Ether Dendrimers in ...
The first dendrimer-supported synthesis of oligothiophenes is reported. The dendrimer serves both as a solubilizing group and a “handle” to facilitate the iterative synthesis of... -
Total Synthesis of the Ristocetin Aglycon
The first total synthesis of the ristocetin aglycon is described employing a modular and highly convergent strategy. An effective 12-step (12% overall) synthesis of the ABCD... -
Phase-Vanishing Reactions that Use Fluorous Media as a Phase Screen. Facile, ...
In fluorous triphasic reactions, such as bromination of alkenes by dibromine and dealkylation of aromatic ethers by boron tribromide, the middle fluorous phase acts as a liquid... -
Palladium-Catalyzed Aromatic C−H Halogenation with Hydrogen Halides by Means ...
A new strategy for catalytic functionalization of C−H bonds by means of electrochemical oxidation is described. Combination of palladium-catalyzed aromatic C−H bond cleavage and... -
Al-Containing Porous Titanium Dioxide Networks: Sol−Gel Synthesis within Aga...
Al-containing titania porous networks have been produced by conducting sol−gel chemistry within the porous structures of agarose gels. The use of the agarose template gives... -
The Dark Side of Crystal Engineering: Creating Glasses from Small Symmetric ...
Glasses made from compounds of low molecular weight are useful materials with many attractive features, including well-defined compositions. At present, there are no reliable... -
Rigid Oligonaphthalenediimide Rods as Transmembrane Anion−π Slides
We report the design, synthesis, and evaluation of rigid oligonaphthalenediimide (O-NDI) rods that are expected to act as transmembrane anion−π slides. Studies in fluorogenic... -
Digestion and Absorption of Ferulic Acid Sugar Esters in Rat Gastrointestinal...
We estimated the absorption site and absorptivity of ferulic acid (FA) and its sugar esters, namely 5-O-feruloyl-l-arabinofuranose (FAA) and feruloyl−arabinoxylan (FAXn), in... -
Debromination of Polybrominated Diphenyl Ethers by Nanoscale Zerovalent Iron:...
The debromination of selected polybrominated diphenyl ethers (PBDEs) by nanoscale zerovalent iron particles (nZVI) was studied to investigate the degradation pathways and the... -
Dual Memory of Enantiomeric Helices in a Polyacetylene Induced by a Single En...
We report the dual memory of both the enantiomeric right- and left-handed helical conformations induced in a polyacetylene based on the temperature-stimulated helicity inversion... -
Highly Enantioselective Hydrogenative Desymmetrization of Bicyclic Imides Lea...
Highly enantioselective hydrogenative desymmetrization of bicyclic imides has been developed with chiral Cp*Ru(PN) catalysts. The present hydrogenation directly provides... -
Defect-Site Promoted Surface Reorganization in Nanocrystalline Ceria for the ...
Defect-site enriched nanocrystalline ceria prepared by an alcoholysis method favors oxidative dehydrogenation of ethylbenzene using nitrous oxide with high conversion and... -
Planar Chiral Cyclic Ether: Asymmetric Resolution and Chirality Transformation
Remarkably stable planar chirality was found in a nine-membered diallylic cyclic ether. Enantiomerically enriched ether was prepared by a kinetic resolution of a racemic one,... -
Chiral Brønsted Acid-Catalyzed Inverse Electron-Demand Aza Diels−Alder Reaction
Inverse electron-demand aza Diels−Alder reaction of aldimine with enol ethers proceeded under the influence of a phosphoric acid diester, derived from (R)-BINOL, to give... -

Chiral Crown Ether Pillared Lamellar Lanthanide Phosphonates
A new chiral bridging ligand, 2,2‘-pentaethylene glycol-1,1‘-binaphthyl-6,6‘-bis(phosphonic acid), was synthesized in 40.7% overall yield in five steps and used to generate... -
Reactions of Strained Hydrocarbons with Alkene and Alkyne Metathesis Catalysts
Here we describe the metathesis reactions of a strained eight-membered ring that contains both alkene and alkyne functionality. We find that the alkyne metathesis catalyst... -
