Ruthenium(II)–arene and triruthenium-carbonyl cluster complexes with new water-soluble phopsphites based on glucose: Synthesis, characterization and antiproliferative activity

Paul Joseph Dyson, Alexey Nazarov, Olivier Pierre Zava

New water-soluble 3,5,6-bicyclophosphite ligands based on glucose modified with uracil, 5-fluorouracil or thymine are reported. The phosphite ligands were subsequently reacted with bis[dichlorido(η6-p-cymene)ruthenium(II)] and trirutheniumdodecacarbonyl to ...

Anti-fibrotic effect of ketoprofen-grafted alginate microcapsules in the transplantation of insulin producing cells

Sandrine Gerber, François Rémi Pierre Noverraz, Daniel Ortiz Trujillo, Luca Szabó, Léo Bühler

The controlled release of small molecular modulators of the immune response from hydrogel microspheres (MS) used for cell immobilization is an attractive approach to reduce pericapsular fibrotic overgrowth (PFO) after transplantation. Ketoprofen is a well- ...

Highly Enantioselective Rhodium(I)-Catalyzed Carbonyl Carboacylations Initiated by C-C Bond Activation

Nicolai Cramer, Laetitia Marie Mélanie Souillart

The lactone motif is ubiquitous in natural products and pharmaceuticals. The Tishchenko disproportionation of two aldehydes, a carbonyl hydroacylation, is an efficient and atom-economic access to lactones. However, these reaction types are limited to the t ...

Organic molecules as mediators and catalysts for photocatalytic and electrocatalytic CO2 reduction

Xile Hu, Yeonji Oh

Reduction of CO2 by electrochemical and photoelectrochemical methods to produce carbon-rich fuels is a heavily pursued research theme. Most of the current efforts are focused on the development of transition-metal-based catalysts. In this tutorial review, ...

Ligand synthesis for homogeneous catalysis : from tertiary monophosphines to atropisomeric bisphosphines

Michael Maurin

Organophosphorus compounds found applications in varied fields of the organic chemistry: they are particularly present in natural compounds such as the deoxyribonucleic acid (DNA) and in the field of catalysis in which their utility is also proven. Thus, t ...
