N-(Pyrid-2-yl)-substituted azolium and pyridinium salts, precursors for hybrid NHC-containing ligands, were obtained with excellent regioselectivity, employing a deoxygenative CH-functionalization of pyridine-N-oxides with substituted imidazoles, thiazoles, and pyridine. Unlike the traditional SNAr-based methods, this approach provides high yields for substrates bearing substituents of different electronic nature. The utility of azolium and pyridinium salts thus prepared was also highlighted by the synthesis of pyridyl-substituted imidazolyl-2-thione, benzodiazepine as well as 2-aminopyridines.

We report a mild palladium-catalyzed selective dehydrogenation of 4-alkylpyridines that exploits their soft enolization to alkylidene dihydropyridines using allyl chloroformate under metal-free conditions. Treatment of these intermediates with a palladium catalyst liberates an alkylpyridylic anion and an allylpalladium(II) intermediate, which combine and undergo beta-hydride elimination to install a double bond. Importantly, the formation of gas byproducts makes the process very practical. Furthermore, the reaction tolerates a broad range of functional groups, including many that can be dehydrogenated using similar palladium-catalyzed reactions, and is selective for 4-alkylpyridines even in substrates bearing multiple pyridylic positions.

We herein report two complementary strategies employing organolithium chemistry for the synthesis of glyoxal derivatives. Micro-mixer technology allows for the generation of unstable organometallic intermediates and their instantaneous in-line quenching with esters as electrophiles. Selective mono-addition was observed via putative stabilized tetrahedral intermediates. Advantages offered by flow chemistry technologies facilitate direct and efficient access to masked 1,2-dicarbonyl compounds while mitigating undesired by-product formation. These two approaches enable the production of advanced and valuable synthetic building blocks for heterocyclic chemistry with throughputs of grams per minute.

The reaction of (dppBIAN) FeCl2 with 3 equivalents of n-BuLi affords a catalytically active anionic Fe complex; the nature of the anionic complex was probed using EPR and IR experiments and is proposed to involve a dearomatized, radical, ligand scaffold. This complex is an active catalyst for the hydrosilylation of esters to afford alcohols; loadings as low as 1 mol% were employed.

Direct alkylation and arylation of allylic C(sp3)-H bonds are straight-forward approaches for accessing allylic C-C products. However, the engagement of allylic C-C bond- forming reaction without introducing extraneous functional groups and stoichiometric oxidant or reductant has proved difficult. Here, we report a general and mild strategy using semiconductor quantum dots (QDs) as photocatalysts for coupling a broad range of available allylic C(sp(3))-H bonds with alpha- amino C-H bonds or heteroarenes, respectively, under sunlight irradiation (> 85 examples). The protocol bypasses stoichiometric oxidant or reductant and pre-functionalization of both the coupling partners and produces hydrogen (H-2) as the byproduct. The outstanding efficiency and selectivity and step- and atom-economy represents the first direct alkylation and arylation of allylic C(sp(3))-H bonds with hydrogen evolution powered by solar energy.

Practical, efficient, and general methods for the diversification of N-heterocycles have been a recurrent goal in chemical synthesis due to the ubiquitous influence of these motifs within bioactive frameworks. Here, we describe a direct, catalytic, and selective functionalization of azines via silylium activation. Our catalyst design enables mild conditions and a remarkable functional group tolerance in a one-pot setup.

The Rotimer, a rotifer-specific biopolymer, is an exogenic bioactive exudate secreted by different monogonant species (e.g. Euchlanis dilatata or Lecane bulla). The production of this viscoelastic biomolecule is induced by different micro-particles, thereby forming a special Rotimer-Inductor Conglomerate (RIC) in a web format. In this case, the water insoluble Carmine crystals, filtered to size (max. diameter was 50 mu m), functioned as an inductor. The RIC production is an adequate empirical indicator to follow up this filamentous biopolymer secretion experientially; moreover, this procedure is very sensitive to the environmental factors (temperature, pH, metals and possible natural pollutant agents). The above mentioned species show completely different reactions to these factors, except to the presence of calcium and to the modulating effects of different drugs. One of the novelties of this work is that the Rotimer secretion and consequently, the RIC-formation is a mutually obligatory and evolutionary calcium-dependent process in the concerned monogonants. This in vivo procedure needs calcium, both for the physiology of animals and for fiber formation, particularly in the latter case. The conglomerate covered area (%) and the detection of the longest filament (mm) of the given RIC were the generally and simultaneously applied methods in the current modulating experiments. Exploring the regulatory (e.g. calciumdependency) and stimulating (e.g. Lucidril effect) possibilities of biopolymer secretion are the basis for optimizing the RIC-production capacities of these micro-metazoans.

A three-descriptor quantitative structure-activity/toxicity relationship (QSAR/QSTR) model was developed for the skin permeability of a sufficiently large data set consisting of 274 compounds, by applying support vector machine (SVM) together with genetic algorithm. The optimal SVM model possesses the coefficient of determination R-2 of 0.946 and root mean square (rms) error of 0.253 for the training set of 139 compounds; and a R-2 of 0.872 and rms of 0.302 for the test set of 135 compounds. Compared with other models reported in the literature, our SVM model shows better statistical performance in a model that deals with more samples in the test set. Therefore, applying a SVM algorithm to develop a nonlinear QSAR model for skin permeability was achieved.
