Ligand‐Controlled Regiodivergent Nickel‐Catalyzed Annulation of Pyridones
Authors: Donets Pavel A. , Cramer Nicolai 
Published: November 2014

AbstractThe 1,6‐annulated 2‐pyridone motif is found in many biologically active compounds and its close relation to the indolizidine and quinolizidine alkaloid core makes it an attractive building block. A nickel‐catalyzed CH functionalization of 2‐pyridones and subsequent cyclization affords 1,6‐annulated 2‐pyridones by selective intramolecular olefin hydroarylation. The switch between the exo‐ and endo‐cyclization modes is controlled by two complementary sets of ligands. Irrespective of the ring size, the regioselectivity during the cyclization is under full catalyst control. Simple cyclooctadiene promotes an exo‐selective cyclization, whereas a bulky N‐heterocyclic carbene ligand results in an endo‐selective mode. The method was further applied in the synthesis of the lupin alkaloid cytisine.
Catalyst‐Controlled Stereoselective Olefin Metathesis as a Principal Strategy in Multistep Synthesis Design: A Concise Route to (+)‐Neopeltolide
Authors: Yu Miao , Schrock Richard R. , Hoveyda Amir H. 
Published: November 2014

AbstractMolybdenum‐, tungsten‐, and ruthenium‐based complexes that control the stereochemical outcome of olefin metathesis reactions have been recently introduced. However, the complementary nature of these systems through their combined use in multistep complex molecule synthesis has not been illustrated. A concise diastereo‐ and enantioselective route that furnishes the anti‐proliferative natural product neopeltolide is now disclosed. Catalytic transformations are employed to address every stereochemical issue. Among the featured processes are an enantioselective ring‐opening/cross‐metathesis promoted by a Mo monoaryloxide pyrrolide (MAP) complex and a macrocyclic ring‐closing metathesis that affords a trisubstituted alkene and is catalyzed by a Mo bis(aryloxide) species. Furthermore, Z‐selective cross‐metathesis reactions, facilitated by Mo and Ru complexes, have been employed in the stereoselective synthesis of the acyclic dienyl moiety of the target molecule.
A transient event in AD 775 reported by al‐Tabarī: A bolide – not a nova, supernova, or kilonova
Authors: Neuhäuser R. , Kunitzsch P. 
Published: November 2014

AbstractGiven that the cause for the strong increase in 14C in AD 774/5 in Japanese and German trees is still a matter of debate (e.g. short gamma‐ray burst or solar super‐flare), we have searched in Arabic chronicles for reports about unusual transient celestial events. In the History of al‐Tabarī we found two (almost identical) reports about such an event. The group around caliph al‐Mansūr observed a transient event while on the way from Baghdad to Mecca on AD 775 Augusst 29– September 1 (Julian calendar). A celestial object (kawkab) was seen to fall or set (inqadda), and its trace (atharuhu) was seen for at least tens of minutes (up to 70–90 min) during morning twilight. The reports use the Arabic words kawkab and athar(uhu), which were also used in the known Arabic reports about supernovae SN 1006 and 1054, so that one might consider an interpretation as a nova‐like event. The kawkab (celestial object) was observed only during the morning twilight at a brightness of probably between about –3 and 0 mag. Such a brightness and time‐scale would be expected for optical kilonovae (at ∼3 to 9 kpc) in the context of short gamma‐ray bursts. There are no similar reports from eastern Asia for this time. However, the short reports are fully consistent with a bolide: The word kawkab can be used for meteor, the verb inqad. d. a normally means falling down, the word atharuhu can mean its trace. We therefore prefer the interpretation as bolide. We discuss in detail how to convert the Muslim calendar date to a date in the Julian calendar using first the calculated Islamic calendar and then considering the time when the crescent new moon could be visible at the given location.

An Optimized Design of Choice Experiments: A New Approach for Studying Decision Behavior in Choice Task Experiments
Authors: Pfeiffer Jella , Duzevik Dejan , Rothlauf Franz , Bonabeau Eric , Yamamoto Koichi 
Published: November 2014

AbstractIn this paper, we present a new approach for the optimal experimental design problem of generating diagnostic choice tasks, where the respondent's decision strategy can be unambiguously deduced from the observed choice. In this new approach, we applied a genetic algorithm that creates a one‐to‐one correspondence between a set of predefined decision strategies and the alternatives of the choice task; it also manipulates the characteristics of the choice tasks. In addition, this new approach takes into account the measurement errors that can occur when the preferences of the decision makers are being measured. The proposed genetic algorithm is capable of generating diagnostic choice tasks even when the search space of possible choice tasks is very large. As proof‐of‐concept, we used this novel approach to generate respondent‐specific choice tasks with either low or high context‐based complexity that we operationalize by the similarity of alternatives and the conflict between alternatives. We find in an experiment that an increase in the similarity of the alternatives and an increase in the number of conflicts within the choice task lead to an increased use of non‐compensatory strategies and a decreased use of compensatory decision strategies. In contrast, the size of the choice tasks, measured by the number of attributes and alternatives, only weakly influences the strategy selection. Copyright © 2014 John Wiley & Sons, Ltd.
Effect of capping agent concentration on thermoluminescence and photoluminescence of copper‐doped zinc sulfide nanoparticles
Authors: Wanjari Lata , Bisen D. P. , Brahme Namita , Sahu Ishwar Prasad , Sharma Ravi 
Published: November 2014

AbstractCopper‐doped zinc sulfide (ZnS:Cu) nanoparticles with varying concentrations of capping agent were prepared using a chemical route technique. These particles were characterized by scanning electron microscopy (SEM), transmission electron microscopy and X‐ray diffraction (XRD). Optical absorption studies showed that the absorption edge shifted towards the blue region as the concentration of the capping agent increased. Using effective mass approximation, calculation of the nanoparticle size indicated that effective band gap energy increases with decreasing particle size. The thermoluminescence (TL) properties of sodium hexameta phosphate (SHMP)‐passivated ZnS:Cu nanoparticles were investigated after UV irradiation at room temperature. The TL glow curve of capped ZnS:Cu showed variations in TL peak position and intensity with the change in capping agent concentration. The photoluminescence (PL) spectra of ZnS:Cu nanoparticles excited at 254 nm exhibited a broad green emission band peaking around 510 nm, which confirmed the characteristic feature of Zn2+ as well as Cu2+ ions as the luminescent centres in the lattice. The PL spectra of ZnS:Cu nanoparticles with increasing capping agent concentrations revealed that the emission becomes more intense and shifted towards shorter wavelengths as the sizes of the samples were reduced.
