Image_1_Midfrontal Theta and Posterior Parietal Alpha Band Oscillations Support Conflict Resolution in a Masked Affective Priming Task.TIF

<p>Past attempts to characterize the neural mechanisms of affective priming have conceptualized it in terms of classic cognitive conflict, but have not examined the neural oscillatory mechanisms of subliminal affective priming. Using behavioral and electroencephalogram (EEG) time frequency (TF) analysis, the current study examines the oscillatory dynamics of unconsciously triggered conflict in an emotional facial expressions version of the masked affective priming task. The results demonstrate that the power dynamics of conflict are characterized by increased midfrontal theta activity and suppressed parieto-occipital alpha activity. Across-subject and within-trial correlation analyses further confirmed this pattern. Phase synchrony and Granger causality analyses (GCAs) revealed that the fronto-parietal network was involved in unconscious conflict detection and resolution. Our findings support a response conflict account of affective priming, and reveal the role of the fronto-parietal network in unconscious conflict control.</p

Reactions of HDDA-Derived Benzynes with Perylenes: Rapid Construction of Polycyclic Aromatic Compounds

Benzynes produced by the thermal cycloisomerization of tetrayne substrates [i.e., by the hexadehydro-Diels–Alder (HDDA) reaction] react with perylenes to produce novel naphthoperylene derivatives. Cyclic voltammetry and absorption and emission properties of these compounds are described. DFT studies shed additional light on the dearomatization that accompanies the reaction as well as some of the spectroscopic behavior

Photochemical Hexadehydro-Diels–Alder Reaction

We demonstrate that the hexadehydro-Diels–Alder (HDDA) cycloisomerization reaction to produce reactive benzyne derivatives can be initiated photochemically. As with the thermal variant of the HDDA process, the reactive intermediates are formed in the absence of reagents or the resulting byproducts required for the generation of benzynes by traditional methods. This photo-HDDA (or hν-HDDA) reaction occurs at much lower temperatures (including even at −70 °C) than the thermal HDDA, but the benzynes produced behave in the same fashion with respect to their trapping reactions, suggesting they are of the same electronic state

The other two data sets were obtained under agreements restricting the publication of raw data, but simulation results and figures can still be generated for these data sets.</p> <p>Requirements: Python 2.x and the following Python modules: numpy, scipy, matplotlib, and mpmath. Two additional modules, mpl_toolkits, and mpl_toolkits.basemap, are required for generating the figures.</p> <p>All files should be placed in a single directory and the data.zip file should be extracted into that directory. The analyses can then be replicated by running the following commands from the command line.</p> <p>Run all analyses and generate figures: python mete_sads.py ./data/ all</p> <p>Run portions of the analysis pipeline:<br> Empirical analyses: python mete_sads.py ./data/ empir<br> Simulation analyses: python mete_sads.py ./data/ sims<br> Figures: python mete_sads.py ./data/ figs</p> <p>On Windows ./data/ should be replaced with .\data\ to match the relevant path conventions.</p> <p>Please note that these analyses involve both a large amount of data and a lot of computational work and therefore take a long time to run. Expect the empirical analysis to take up to a day. Simulations may take up to several weeks on an 8-core server. This can be decreased to about a week by downloading the beta_lookup_table.pck file from the repository described below and placing it in the same folder as the other files. Generating figures takes about one hour due to the neighborhood calculations required for the color ramps on the observed-predicted plots.</p> <p>Version Control Repository: The full version control repository for this project (including post-publication improvements) is publicly available at <a href="https://github.com/weecology/white-et-al-2012">https://github.com/weecology/white-et-al-2012</a>. The code in this repository relies on two additional modules: <a href="https://github.com/weecology/METE">https://github.com/weecology/METE</a> and <a href="https://github.com/weecology/macroecotools">https://github.com/weecology/macroecotools</a>. If you would like to use the code in this Supplement for your own analyses it is strongly suggested that you use the equivalent code in the repositories as this is the code that is being actively maintained and developed.

Stereoselective Synthesis of Indolyl‑<i>C</i>‑glycosides Enabled by Sequential Aminopalladation and Heck Glycosylation of 2‑Alkynylanilines with Glycals

An efficient and general approach for the synthesis of indolyl-C-glycosides via aminopalladation and subsequent Heck-type glycosylation of easily available 2-alkynylanilines and glycals has been developed. This protocol features excellent stereoselectivity, a broad substrate scope, and mild reaction conditions. In addition, 2,3-pseudoglycals also successfully participated in this cascade reaction, affording C2/C3-branched indolyl glycosides with high regio-/stereoselectivity. The utility of this protocol was also demonstrated by a large-scale reaction and diversified synthetic transformations of the desired products
