Adjusting the Local Arrangement of π‑Stacked Oligothiophenes through Hydrogen Bonds: A Viable Route to Promote Charge Transfer

Antonio Prlj, Jérôme Florian Gonthier, Eric Albert Georges Bremond, Hongguang Liu

We show that substituting quaterthiophene cores with strong H-bond aggregators, such as urea groups, provides an efficient way to adjust the mutual in-plane displacements of the semiconducting units and promote charge transfer. Our 2-D structure-property m ...

A four-component organogel based on orthogonal chemical interactions

Kay Severin, Kurt Schenk, Nicolas Luisier

A thermoresponsive organogel was obtained by orthogonal assembly of four compounds using dynamic covalent boronate ester and imine bonds, as well as dative boron-nitrogen bonds. It is shown that the gel state can be disrupted or reinforced by chemicals whi ...

Conformational control of anticancer activity: the application of arene-linked dinuclear ruthenium(II) organometallics

Paul Joseph Dyson, Rosario Scopelliti, Laure Menin, Benjamin Samuel Murray

Dinuclear metal complexes have emerged as a promising class of biologically active compounds which possess unique anticancer activity. Here, we describe a novel series of arene-linked dinuclear organometallic Ru(II) complexes, where the relative conformati ...

(Arene)ruthenium Complexes with Imidazolin-2-imine and Imidazolidin-2-imine Ligands

Rosario Scopelliti, Kay Severin

Imidazolin-2-imine and imidazolidin-2-imine ligands are versatile N donors in transition metal chemistry. Here, we describe the synthesis and characterization of (arene)Ru complexes with these ligands. Simple adducts of the type [(p-cymene)Ru(L)Cl-2] (L = ...

Tetrahydrobiopterin Biosynthesis as an Off-Target of Sulfa Drugs

Kai Johnsson, Florence Pojer, Hirohito Haruki, Miriam Grønlund Pedersen, Katarzyna Irena Gorska

The introduction of sulfa drugs for the chemotherapy of bacterial infections in 1935 revolutionized medicine. Although their mechanism of action is understood, the molecular bases for most of their side effects remain obscure. Here, we report that sulfamet ...

Adducts of Nitrous Oxide and N-Heterocyclic Carbenes: Syntheses, Structures, and Reactivity

Rosario Scopelliti, Kay Severin, Euro Solari, Basile Vuichoud, Alexander Tskhovrebov

N-Heterocyclic carbenes (NHCs) react at ambient conditions with nitrous oxide to give covalent adducts. In the crystal, all compounds show a bent N2O group connected via the N-atom to the former carbene carbon atom. Most adducts are stable at room temperat ...

Catalytic Enantioselective Michael Addition of α-Aryl-α-Isocyanoacetates to Vinyl Selenone: Synthesis of α,α-Disubstituted α-Amino Acids and (+)- and (−)-Trigonoliimine A

Qian Wang, Jieping Zhu, Thomas Bertrand Pascal Marie Buyck

Be like Mike: The title reaction in the presence of the catalyst 1 afforded Michael adducts in excellent yields and enantioselectivities. The adducts were readily converted into alpha,alpha’-disubstituted alpha-amino acids. The enantioselective total synth ...

Pattern-Based Sensing of Peptides and Aminoglycosides with a Single Molecular Probe

Rosario Scopelliti, Kay Severin, Christian Heinis, Shiyu Chen, Bo Ram Lee

A coumarin-based molecular probe can be used for the sensing of peptides and aminoglycoside antibiotics. The probe reacts with the primary amine group(s) of the analytes to give a mixture of covalent adducts with distinct colors. Each analyte gives rise to ...
