Mesomorphism and Photophysics of Some Metallomesogens Based on Hexasubstituted 2,2′:6′, 2′′‐Terpyridines

Published: May 2016

AbstractThe luminescent and mesomorphic properties of a series of metal complexes based on hexacatenar 2,2′:6′,2′′‐terpyridines are investigated using experimental methods and density functional theory (DFT). Two types of ligand are examined, namely 5,5′′‐di(3,4,5‐trialkoxyphenyl)terpyridine with or without a fused cyclopentene ring on each pyridine and their complexes were prepared with the following transition metals: ZnII, CoIII, RhIII, IrIII, EuIII and DyIII. The exact geometry of some of these complexes was determined by single X‐ray diffraction. All complexes with long alkyl chains were found to be liquid crystalline, which property was induced on complexation. The liquid‐crystalline behaviour of the complexes was studied by polarising optical microscopy and small‐angle X‐ray diffraction. Some of the transition metal complexes (for example, those with ZnII and IrIII) are luminescent in solution, the solid state and the mesophase; their photophysical properties were studied both experimentally and using DFT methods (M06‐2X and B3LYP).
Designing Tunable White‐Light Emission from an Aurophilic CuI/AuI Coordination Polymer with Thioether Ligands
Authors: Ovens Jeffrey S. , Christensen Peter R. , Leznoff Daniel B. 
Published: May 2016

AbstractWhite‐light emitters have attracted considerable attention due to their importance in current and future technologies. By incorporating molecular fragments that independently emit in the blue, green/yellow, and red visible regions, specifically Cu‐NC, Au⋅⋅⋅Au interactions, and Cu‐SR2, respectively, into a single material, new white‐light‐emitting systems have been targeted. With this goal, three new CuI/thioether‐based coordination polymers containing bridging [Au(CN)2]− units have been synthesized and structurally characterized, and their photoluminescence properties (at room and low temperatures) have been delineated. Using this approach, white‐light emission (tunable from slightly yellow to slightly blue, depending on λex) is generated from Cu(Me2S)[Au(CN)2], a feature uncommon in such simple coordination compounds.
Challenges and Perspectives in Designing Artificial Photosynthetic Systems

Published: May 2016

AbstractThe development of artificial photosynthetic systems for water splitting and CO2 reduction on a large scale for practical applications is the ultimate goal towards worldwide sustainability. This Concept highlights the state‐of‐the‐art research trends of artificial photosynthesis concepts and designs from some new perspectives. Particularly, it is focused on five important aspects for the design of promising artificial photosynthetic systems: 1) catalyst development, 2) architecture design, 3) device buildup 4) mechanism exploration, and 5) theoretical investigations. Some typical progress and challenges, the most significant milestones achieved to date, as well as possible future directions are illustrated and discussed. This Concept article presents a selection of new developments to highlight new trends and possibilities, main barriers, or challenges; with this, we hope to inspire more advances in the field of artificial photosynthesis.
Discovery, Total Synthesis and Key Structural Elements for the Immunosuppressive Activity of Cocosolide, a Symmetrical Glycosylated Macrolide Dimer from Marine Cyanobacteria

AbstractA new dimeric macrolide xylopyranoside, cocosolide (1), was isolated from the marine cyanobacterium preliminarily identified as Symploca sp. from Guam. The structure was determined by a combination of NMR spectroscopy, HRMS, X‐ray diffraction studies and Mosher's analysis of the base hydrolysis product. Its carbon skeleton closely resembles that of clavosolides A–D isolated from the sponge Myriastra clavosa, for which no bioactivity is known. We performed the first total synthesis of cocosolide (1) along with its [α,α]‐anomer (26) and macrocyclic core (28), thus leading to the confirmation of the structure of natural 1. The convergent synthesis featured Wadsworth–Emmons cyclopropanation, Sakurai annulation, Yamaguchi macrocyclization/dimerization reaction, α‐selective glycosidation and β‐selective glycosidation. Compounds 1 and 26 potently inhibited IL‐2 production in both T‐cell receptor dependent and independent manners. Full activity requires the presence of the sugar moiety as well as the intact dimeric structure. Cocosolide also suppressed the proliferation of anti‐CD3‐stimulated T‐cells in a dose‐dependent manner.

Ordered Layered Dendrimers Constructed from Two Known Dendrimer Families: Inheritance and Emergence of Properties

AbstractA new concept is presented, namely the synthesis of dendrimers intrinsically composed in alternation of building blocks pertaining to two known families of dendrimers: phosphorhydrazone dendrimers and triazine–piperazine dendrimers. These mixed dendrimers with layered controlled architecture inherit their easy 31P NMR characterization and their thermal stability from the phosphorhydrazone family, and their decreased solubility from the triazine–piperazine family. However, they have also their own and original characteristics. Both parent families are white powders, whereas the mixed dendrimers are yellow, orange, or red powders, depending on the generation. DFT calculations were carried out on model dendrons to understand these special color features. Remarkably, these dendrimers incorporating redox‐active organic entities allow for the first time the monitoring of the growth of an organic dendrimer by electrochemistry while highlighting an even–odd generation behavior.

Published: May 2016

AbstractA MgII‐mediated catalytic asymmetric dearomatization (CADA) reaction of β‐naphthols has been developed. The reaction proceeds under ambient temperature and give a series of chiral trisubstituted olefins with good chemoselectivities, Z/E ratios, and excellent enantioselectivities. A fluorinated β‐naphthol was designed to generate chiral organofluorine skeletons through the current CADA reaction. Moreover, an interesting tandem cyclization reaction was observed in the following transformation process through an undiscovered intramolecular hydride transfer pathway.

Published: May 2016

AbstractThe use of an equivalent amount of an organic base leads to high enantiomeric excess in the asymmetric hydrogenation of N‐benzylated 3‐substituted pyridinium salts into the corresponding piperidines. Indeed, in the presence of Et3N, a Rh‐JosiPhos catalyst reduced a range of pyridinium salts with ee values up to 90 %. The role of the base was elucidated with a mechanistic study involving the isolation of the various reaction intermediates and isotopic labeling experiments. Additionally, this study provided some evidence for an enantiodetermining step involving a dihydropyridine intermediate.
Catalytic, Cascade Ring‐Opening Benzannulations of 2,3‐Dihydrofuran O,O‐ and N,O‐Acetals
Authors: Aponte‐Guzmán Joel , Phun Lien H. , Cavitt Marchello A. , Taylor J. Evans , Davy Jack C. , France Stefan 
Published: May 2016

AbstractAn Al(OTf)3‐catalyzed intramolecular cascade ring‐opening benzannulation of 2,3‐dihydrofuran O,O‐ and N,O‐acetals is described. The cascade sequence involves the dihydrofuran ring‐opening by acetal hydrolysis, an intramolecular Prins‐type cyclization, and aromatization to generate an array of benzo‐fused (hetero)aromatic systems in up to 95 % yield. This method represents the first example of dihydrofuran acetal usage in benzannulation reactions. The approach provides excellent regiocontrol based on the choice of alkenes used to form the requisite dihydrofuran acetals.
