Two-Step Synthesis of Linear and Bent Dicarboxylic Acid Metalloligands with Lengths of up to 3 nm

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Suzanne Maria Jansze, Ophélie Marie Planes

Nanometer-sized polycarboxylate ligands are interesting building blocks for metallasupramolecular chemistry, but access to these compounds is often limited by complicated synthetic pathways. Here, we describe a simple two-step protocol, which allows prepar ...

Towards the Sarpagine-Ajmaline-Macroline Family of Indole Alkaloids: Enantioselective Synthesis of an N-Demethyl Alstolactone Diastereomer

Qian Wang, Jieping Zhu, Dylan Jean Robert Dagoneau

the strategy involving the use of functionalized tetrahydro-6H-cycloocta[b]indol-6-one is reported as a key intermediate for synthesis of members of the sarpagine-ajmaline-macroline family of monoterpene indole alkaloids. The desired tricycle was synthesiz ...

Extent of N-terminus exposure of monomeric alpha-synuclein determines its aggregation propensity

Hilal Lashuel, Anass Chiki

As an intrinsically disordered protein, monomeric alpha-synuclein (aSyn) occupies a large conformational space. Certain conformations lead to aggregation prone and non-aggregation prone intermediates, but identifying these within the dynamic ensemble of mo ...

Chiral Cyclopentadienyl Ligands: Design, Syntheses, and Applications in Asymmetric Catalysis

Nicolai Cramer, Benoît Daniel Bertrand Audic

The creation of new chiral ligands capable of providing high stereocontrol in metal-catalyzed reactions is crucial in modern organic synthesis. The production of bioactive molecules as single enantiomers is increasingly required, and asymmetric catalysis w ...

Iridium-catalyzed acid-assisted asymmetric hydrogenation of oximes to hydroxylamines

Nicolai Cramer

Asymmetric hydrogenations are among the most practical methods for the synthesis of chiral building blocks at industrial scale. The selective reduction of an oxime to the corresponding chiral hydroxylamine derivative remains a challenging variant because o ...

Hexayne Amphiphiles and Bolaamphiphiles

Rosario Scopelliti, Holger Frauenrath, Enzo Jean Raymond Bomal, Reuben Yeo Jueyuan, Vincent Matthieu Guillaume Croué

Oligoynes with two or more conjugated carbon-carbon triple bonds are useful precursors for carbon-rich nanomaterials. However, their range of app0lications has so far been severly limited by the challenging syntheses, particularly in the case of oligoynes ...

Reversibly Cross-Linking Polymer Brushes Using Interchain Disulfide Bonds

Harm-Anton Klok, Piotr Mocny

The introduction of interchain cross-links in surface-grafted polymer brushes increases the robustness and mechanical properties of these thin polymer films. In most cases, cross-linked polymer brushes contain permanent interchain cross-links. The use of r ...

Synthesis of DNA‐encoded disulfide‐ and thioether‐cyclized peptides

Christian Heinis, Van Manh Pham

DNA-encoded chemical library technologies enable the screening of large combinatorial libraries of chemically and structurally diverse molecules, including short cyclic peptides. A challenge in the combinatorial synthesis of cyclic peptides is the final st ...
