Abstract Citronellol, one of the most used fragrance compounds worldwide, is one ingredient of Fragrance Mix II used to assess skin allergy to fragrances in dermatitis patients. Pure citronellol is non-allergenic. Main issue is it autoxidizes when exposed to air becoming then allergenic. The…
Abstract IspG (also called GcpE) is an oxygen-sensitive [4Fe-4S] enzyme catalyzing the penultimate step of the methylerythritol phosphate (MEP) pathway, a validated target for drug development. It converts 2-C-methyl-d-erythritol-2,4-cyclo-diphosphate (MEcPP) into (E)-4-hydroxy-3-methyl-but-2-enyl-…
Abstract The non-mevalonate or also called MEP pathway is an essential route for the biosynthesis of isoprenoid precursors in most bacteria and in microorganisms belonging to the Apicomplexa phylum, such as the parasite responsible for malaria. The absence of this pathway in mammalians makes it an…
Abstract The first synthesis of gem-difluorinated ene–ynamides is presented via deprotonation of trifluoromethylated N-allenamides and δ extrusion of fluorine. These highly reactive building blocks, owing to their dual functional groups, offer a unique entry to difluorinated dienes and to…
Abstract A synthesis of new-to-nature aza-iridoids via ynamides is presented. ZrCl4 proved to be the best acid to perform this transformation. Various ynamides were accommodated, and seco-iridoids could be obtained as well. Aza-iridoids were infiltrated into leaves of Scrophularia Nodosa, an…
L'Institut de Chimie de Strasbourg a le plaisir de vous annoncer que l'article « Inorganic phosphate in growing calcium carbonate abalone shell suggests a shared mineral ancestral precursor » récemment publié dans Nature Communication, auquel Philippe Bertani (équipe Biophysique des membranes et RMN…
Abstract Combination of spin crossover metal ion and open-shell environment results in the mixing of high- and low- spin metal states, named as spinmerism.
Abstract Diaryl ditelluride derivatives bearing different functional groups were prepared with the aim to study their ability to interact through chalcogen bonding (ChB). Rectangular Te4 and triangular Te3 motifs were observed in the solid-state as a result of intermolecular Te⋅⋅⋅Te ChB. In…
Abstract N-Allenamides, substituted by an ester at the γ-position, were obtained through addition of terminal ynamides with ethyl diazoacetate under copper catalysis for the first time. Regio- and stereoselective hydroamination of those activated N-allenamides provided exclusively E-configured…
Abstract Quantum embedding is a divide and conquer strategy that aims at solving the electronic Schrödinger equation of sizeable molecules or extended systems. We establish in the present work a clearer and in-principle-exact connection between density matrix embedding theory (DMET) and…
Abstract A major research topic consists of revealing the contribution of radical-mediated reactions in dermatological diseases related to xenobiotic-induced stress to succeed risk-assessment procedures protecting producers and consumers. Allergic contact dermatitis is the clinically relevant…
Summary Chiral gold(I) acetylide trinuclear complexes 1 - 3 based on the cyclotribenzylene platform and terminal PR3 ligands (R = Ph, Et, and Cy, respectively), were characterized and their light emission studied. They exhibited long-lived blue phosphorescence in CHCl3 and a weak fluorescence in…
Abstract The theory developed in an accompanying paper [Déjardin, Phys. Rev. E105, 024109 (2022)] is used to compute the Kirkwood correlation factor of simple polar fluids of different nature. From this calculation, the theoretical static permittivity is readily obtained, which is compared with…
Abstract A copper-mediated coupling reaction between ynamides and diazo-compounds to produce N -allenamides is reported for the first time. This method enables facile and rapid access to terminal N -allenamides by using commercially available TMS-diazomethane with wide functional group…
Tweet IFM proposes PrepFlow, a new toolkit for chemical library preparation and management. This open-access software is expected to boost the exploitation of big data in Chemistry for structure-based drug discovery.
Abstract Recent progress in the field of (time-independent) ensemble density-functional theory (DFT) for excited states are reviewed. Both Gross–Oliveira–Kohn (GOK) and N-centered ensemble formalisms, which are mathematically very similar and allow for an in-principle-exact description of neutral…
Summary We report the design of a unique bioinspired ligand merging redox-active catechol and flavin-related alloxazine substructures. Upon coordination with a Ni(II) salt, this hybrid ligand forms a trinuclear complex containing three NiII centers and three redox-active ligands. This air-stable…
Vous trouverez à l'adresse ci-dessous un numéro spécial des Comptes Rendus Chimie consacré au GDR MAPYRO avec plusieurs articles en accès libre des équipes LECPCS, LSAMM, CLAC (Institut de Chimie de Strasbourg, UMR 7177). You will find at the address below a special issue of the “Comptes Rendus…
Abstract Winning combo: Porphyrins and polyoxometalates can be combined into useful architectures for energy conversion, this minireview highlights the most successful strategies developed to date.
Abstract In an effort to determine the thermochemistry of established organometallic transformation, the well documented reaction of alkynes with a palladacycle was investigated by isothermal titration calorimetry (ITC). Although the mechanism of the insertion of unsaturated substrates into the…
