Published: September 2014

AbstractWe report an investigation into analogues of the thrombin binding aptamer (TBA). Individual thymidines were replaced by the unusual residue 5‐hydroxymethyl‐2′‐deoxyuridine (hmU). This differs from the canonical thymidine by a hydroxyl group on the 5‐methyl group. NMR and CD data clearly indicate that all TBA derivatives retain the ability to fold into the “chair‐like” quadruplex structure. The presence of the hmU residue does not significantly affect the thermal stability of the modified aptamers compared to the parent, except for analogue H9, which showed a marked increase in melting temperature. Although all TBA analogues showed decreased affinities to thrombin, H3, H7, and H9 proved to have improved anticoagulant activities. Our data open up the possibility to enhance TBA biological properties, simply by introducing small chemical modifications.

Published: September 2014

AbstractA one‐pot synthesis of palladium nanoparticles supported on magnesium hydroxide fluoride has been performed with the fluorolytic sol–gel method. The prepared catalysts were characterized by using various physicochemical techniques. The sol–gel method led to high surface area (>135 m2 g−1), mesoporous catalysts (pore volume=0.19–0.23 cm3 g−1, pore diameter=3–5 nm) with uniformly dispersed palladium nanoparticles approximately 2 nm in diameter on the surface. The catalysts synthesized by using different concentrations of aqueous hydrofluoric acid exhibited changing surface and acidic properties. Very high dispersion of palladium on magnesium fluoride (47 %) was obtained with 1 wt % palladium loading. The catalysts were used for hydrogenation of various olefins in the presence of other organic functionalities at room temperature and atmospheric hydrogen pressure. Various substituted olefins were hydrogenated with almost 100 % conversion and selectivity. The catalysts were recycled efficiently over five cycles without appreciable loss in catalytic activity. There was no palladium leaching under the reaction conditions, which was confirmed by inductively coupled plasma atomic emission spectroscopy analysis. Activation of olefin on the catalyst surface could not be observed by in situ FTIR studies, indicating facile activation of hydrogen on the palladium supported on magnesium hydroxide fluoride.

Interactions of Bis(2,4,4‐trimethylpentyl)dithiophosphinate with NdIII and CmIII in a Homogeneous Medium: A Comparative Study of Thermodynamics and Coordination Modes
Authors: Xu Chao , Rao Linfeng 
Published: September 2014

AbstractComplexation of NdIII and CmIII with purified Cyanex301 (ammonium bis(2,4,4‐trimethylpentyl)dithiophosphinate, denoted as HL) was studied in 1 % v/v water/ethanol under identical conditions by spectrophotometry and microcalorimetry. For NdIII, three successive complexes, NdL2+, NdL2+, and NdL3, formed in the solution. In contrast, four complexes, CmL2+, CmL2+, CmL3, and CmL4− formed during the titration with Cm. Fluorescence lifetime measurements provided additional insight into the complexation of CmIII with Cyanex301. The stepwise stability constants for the CmLj(3−j)+ (j=1–3) complexes are about one order of magnitude higher than the corresponding NdLj(3−j)+ complexes. The enthalpies of complexation are endothermic for both NdIII and CmIII, suggesting that the energy required for desolvation exceeds the energy gained from the cation/ligand combination. Specifically, the enthalpy of complexation for CmL2+ is 3.5 kJ mol−1 less endothermic than that of NdL2+, implying stronger covalent interaction in CmL2+ than NdL2+. However, the enthalpies of complexation for CmL2+ and NdL2+ are nearly identical, and the enthalpy of complexation for CmL3(aq) becomes more endothermic than that for NdL3(aq). The observations suggest that, in the ethanol/water media, the overall energetics of the CmIII/NdIII complexation with Cyanex301 could depend on a number of factors, including the extent of covalency, the degree of desolvation, and the coordination modes.

AbstractThe square‐like homo‐ and heterometallamacrocycles [{Pd(η3‐2‐Me‐C3H4)(Ln)2}2{M(dppp)}2](CF3SO3)6 (dppp=1,3‐bis(diphenylphosphino)propane) and [{Pd(η3‐2‐Me‐C3H4)(L1)2}2{M(PPh3)2}2](CF3SO3)6 [py=pyridine, M=Pd, Pt, Ln=4‐PPh2py (L1), 4‐C6F4PPh2py (L2)] containing allyl corners were synthesised by antisymbiotic self‐assembly of the different palladium and platinum metallic corners and the ambidentate N,P ligands. All the synthesised assemblies displayed a complex dynamic behaviour in solution, the rate of which is found to be dependent on the electronic and/or steric nature of the different building blocks. A kinetico‐mechanistic study by NMR line shape analysis of the dynamics of some of these assemblies was undertaken in order to determine the corresponding thermal activation parameters. Both an enhanced thermodynamic stability and slower dynamics were observed for platinum‐pyridine‐containing species when compared with their palladium analogues. Time‐dependent NMR spectroscopy in combination with ESI mass spectrometry was used to study the exchange between the assemblies and their building blocks, as well as that occurring between different metallamacrocycles. Preliminary studies were carried out on the activity of some of the metallamacrocyclic compounds as catalytic precursors in the allylic substitution reaction, and the results compared with that of the monometallic allylic corner [Pd(η3‐2‐Me‐C3H4)(L1)2]+.
Easy Entry into Reduced Ar‐BIANH2 Compounds: A New Class of Quinone/Hydroquinone‐Type Redox‐Active Couples with an Easily Tunable Potential

Published: September 2014

AbstractAr‐BIANH2 bearing different substituents on the aryl rings have been synthesized in high yield by reduction of the corresponding bis(aryl)acenaphthenequinonediimine (Ar‐BIAN) compounds. The structure of p‐CH3C6H4‐BIANH2 in the solid state was determined by X‐ray diffraction. An exhaustive voltammetric investigation of the two parallel BIAN and BIANH2 series afforded a first rationalization of the redox properties of these molecules, highlighting their analogies with quinone/hydroquinone systems. Such analogies, in combination with the much more negative reduction potential range of Ar‐BIAN compounds with respect to quinones, can afford to extend the range of reduction potentials so far obtainable by the use of quinones.
Periodic Perturbation of Chemical Oscillators: Entrainment and Induced Synchronization
Authors: Makki Rabih , Muñuzuri Alberto P. , Perez‐Mercader Juan 
Published: September 2014

AbstractIt is well known that a large number of catalyst‐carrying beads immersed in an oscillatory chemical medium (Belousov–Zhabotinsky reaction) display collective oscillatory behavior. Using a light sensitive version of BZ, we show that this collective behavior can be entrained to an external light source with an oscillatory intensity. Thus, the emerging collective behavior can be controlled by an external perturbation.

AbstractConstraining small peptides into specific secondary structures has been a major challenge in peptide ligand design. So far, the major solution for decreasing the conformational flexibility in small peptides has been cyclization. An alternative is the use of topological templates, which are able to induce and/or stabilize peptide secondary structures by means of covalent attachment to the peptide. Herein a multicomponent strategy and structural analysis of a new type of peptidosteroid architecture having the steroid as N‐substituent of an internal amide bond is reported. The approach comprises the one‐pot conjugation of two peptide chains (or amino acid derivatives) to aminosteroids by means of the Ugi reaction to give a unique family of N‐steroidal peptides. The conjugation efficiency of a variety of peptide sequences and steroidal amines, as well as their consecutive head‐to‐tail cyclization to produce chimeric cyclopeptide–steroid conjugates, that is, macrocyclic lipopeptides, was assessed. Determination of the three‐dimensional structure of an acyclic N‐steroidal peptide in solution proved that the bulky, rigid steroidal template is capable of both increasing significantly the conformational rigidity, even in a peptide sequence as short as five amino acid residues, and inducing a β‐turn secondary structure even in the all‐s‐trans isomer. This report provides the first evidence of the steroid skeleton as β‐turn inducer in linear peptide sequences.

Published: September 2014

AbstractAn unexpected cationic bis‐N‐heterocyclic carbene (NHC) benzylidene ether based ruthenium complex (2 a) was prepared through the double incorporation of an unsymmetrical unsaturated N‐heterocyclic carbene (U2‐NHC) ligand that bore an N‐substituted cyclododecyl side chain. The isolation and full characterization (including X‐ray diffraction studies) of key synthetic intermediates along with theoretical calculations allowed us to understand the mechanism of the overall cationization process. Finally, the newly developed complex 2 a displayed interesting latent behavior during ring‐closing metathesis, which could be “switched on” under acidic conditions.
Cross‐Metathesis/Isomerization/Allylboration Sequence for a Diastereoselective Synthesis of Anti‐Homoallylic Alcohols from Allylbenzene Derivatives and Aldehydes
Authors: Hemelaere Rémy , Carreaux François , Carboni Bertrand 
Published: September 2014

AbstractWe describe a highly diastereoselective approach to anti‐homoallylic alcohols from allylbenzene derivatives and aldehydes. The strategy is based on a cross‐metathesis/isomerization/allylboration sequence catalyzed successively by ruthenium and iridium. This methodology provides another way to access this class of compounds, which leads to the preparation of hitherto‐unknown homoallylic alcohols without the requirement to control the stereochemistry of the 1‐alkenyl boronate intermediates. Our study towards an enantioselective version of this sequential reaction is also reported.
Titanium Salan Catalysts for the Asymmetric Epoxidation of Alkenes: Steric and Electronic Factors Governing the Activity and Enantioselectivity
Authors: Talsi Evgenii P. , Samsonenko Denis G. , Bryliakov Konstantin P. 
Published: September 2014

AbstractA new insight into the highly enantioselective (up to >99.5 % ee) epoxidation of olefins in the presence of chiral titanium(IV) salan complexes is reported. A series of 14 chiral ligands with varying steric and electronic properties have been designed, and it was found that electronic effects modulate the catalytic activity (without affecting the enantioselectivity), whereas the steric properties account for the enantioselectivity of the epoxidation. Competitive oxidations of p‐substituted styrenes reveal the electrophilic nature of the oxygen‐transferring active species, with a Hammett ρ value of −0.51; the enantioselectivity is unaffected by the electron‐donating (or withdrawing) ability of the p‐substituents. Mechanistic studies provide evidence in favor of a stepwise reaction mechanism: in the first (rate‐determining) stage, olefin most probably coordinates to the active species, followed by intramolecular enantioselective oxygen transfer. The enantioselectivity increases with decreasing temperature. The modified Eyring plots for the epoxidation of styrene and (Z)‐β‐methylstyrene are linear, indicating a single, enthalpy‐controlled mechanism of stereoselectivity, with ΔΔH≠=−6.6 kJ mol−1 and −5.4 kJ mol−1, respectively.

AbstractWe describe here a novel procedure for the synthesis of highly substituted 2‐quinolinones. By this newly developed approach, 2‐quinolinone derivatives were prepared in moderate to good yields by carbonylative cyclization of N‐aryl‐pyridine‐2‐amines and internal alkynes by CH activation. Remarkably, [Mo(CO)6] was applied as a solid CO source and the reaction proceeded in an atom economic manner.
Visible‐Light Promoted Catalyst‐Free Imidation of Arenes and Heteroarenes

Published: September 2014

AbstractWe described herein a catalyst‐free visible‐light photolytic protocol for the imidation of arenes and heteroarenes. N‐Bromosaccharin was identified as a viable and chemoselective nitrogen radical precursor that undergoes controllable homolytic cleavage under ambient light irradiation. The reaction can be applied to a number of arenes and heteroarenes with good chemo‐ and regioselectivity. Mechanistic studies revealed that radical chain termination by electron transfer‐proton transfer (ET‐PT) is the leading productive pathway for the reaction.
