Abstract:
AbstractAcyclic quaternary carbon stereocenters occur frequently in natural products, bioactive molecules, and pharmaceutical compounds. Construction of a carbon stereogenic center attached to four different carbons with defined spatial arrangement is a daunting challenge in asymmetric catalysis. Significant efforts have been directed towards the stereoselective construction of such acyclic quaternary carbon stereocenters. In particular, catalytic generation of acyclic quaternary carbon stereocenters through functionalization of unsaturated hydrocarbons is an extremely attractive approach beca

Abstract:
An efficient enantioselective construction of quaternary carbons including spiro carbons is an area of intense interest due to the importance of these units as components of biologically active natural products. Prominent methods are presented for the synthesis of chiral, nonracemic quaternary carbon centers by (i) stereospecific rearrangement of optically active epoxides, (ii) enzyme-catalyzed resolution, and (iii) hypervalent iodine reagent-induced ipso-substitution of para-substituted phenol derivatives. These methods were applied to the total syntheses of fredericamycin A and discorhabdin

Abstract:
Contiguous quaternary carbons in terpene natural products remain a major challenge in total synthesis. Synthetic strategies to overcome this challenge will be a pivotal prerequisite to the medicinal application of natural products and their analogs or derivatives. In this review, we cover syntheses of natural products that exhibit a dense assembly of quaternary carbons and whose syntheses were uncompleted until recently. While discussing their syntheses, we not only cover the most recent total syntheses but also provide an update on the status quo of modern syntheses of complex natural product

Abstract:
The largest Lapacian eigenvalue ?1 of the molecular graph is a quantity important in the theory of the photoelectron spectra of saturated hydrocarbons. It is shown that in the case of alkanes, the presence or absence of quaternary carbon atoms is the main structural feature on which ?1 depends. Within sets of all alkanes with a given number of carbon atoms the species (with and without quaternary carbons atoms) whose ?1-values are minimal and maximal are determined.

Abstract:
The synthesis of quaternary carbons often requires numerous steps and complex conditions or harsh reagents that act on heavily engineered substrates. This is largely a consequence of conventional polar-bond retrosynthetic disconnections that in turn require multiple functional group interconversions, redox manipulations, and protecting group chemistry. Here, we report a simple catalyst and reductant combination that converts two types of feedstock chemicals, carboxylic acids and olefins, into tetrasubstituted carbons through quaternization of radical intermediates.

Nowadays one of the biggest challenges for carbon materials is their use in CO2 capture and their use as electrocatalysts in the oxygen reduction reaction (ORR). In both cases, it is necessary to dope the carbon with nitrogen species. Conventional methods to prepare nitrogen doped carbons such as melamine carbonization or NH3 treatment generate nitrogen doped carbons with insufficient nitrogen content. In the present research, a series of activated carbons derived from MOFs (ZIF-8, ZIF-67) are presented. Activated carbons have been prepared in a single step, by pyrolysis of the MOF in an inert

Abstract:
Abstract Rotated cage corrosion experiments (4 m/s) were performed with flat coupons of 2 carbon steels (38Mn6/C75, X65) and 3 corrosion resistant alloys [X20Cr13, X2CrNiMoN22-5-3 (1.4462, duplex) and X1NiCrMoCu 25-20-5 (1.4539; alloy 904L)] in water saturated with CO2 under conditions of supercritical carbon dioxide (scCO2). In this corrosion system the performance of inhibitors (oleic acid-based imidazolines, alkenylsuccinic acid anhydrides, and quaternary ammonium salts) was studied at 50, 80, 110 and 130°C using mass loss measurements and topographical scanning (in case of localized attack

Abstract:
Abstract In this work, we perform all-atom molecular dynamics simulations to study the adsorption morphology of alkyldimethylbenzyl ammonium bromides (henceforth referred as q-c molecules). Our simulations reveal that q-c12 molecules (inhibitor molecules with 12 carbon atom long tail) adsorb in an ordered, standing-up orientation on the metal surface, whereas the adsorption of q-c4 molecules (inhibitor molecule with 4 carbon atom long tail) is rather disordered. Our free energy calculations further support that because of an ordered adsorption, a greater number of q-c12 molecules adsorb onto t
