Ferrocenylphosphine-imine ligands for Pd-catalyzed asymmetric allylic alkylation

, 2002
Ferrocenylphosphine-imine ligands 6 derived front (R,S)-PPFNH2-R 5 and a variety of benzaldehydes were applied in the Pd-catalyzed asymmetric allylic alkylation of 1,3-diphenylprop-2-en-1-yl acetate 7a or pivalate 7b with dimethyl malonate.

Protonation‐Induced Electron Density Redistribution Facilitates Aggregation in PNNP Dicopper Hydride Complexes

Chemistry – A European Journal, EarlyView.
Copper(I) hydride complexes often exhibit diverse aggregation behavior that can profoundly influence their structure and reactivity. In this study we use a combined experimental and computational approach to identify key structural an electronic factors that govern aggregation in PNNP dicopperhydride complexes.

Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis

Chemistry – A European Journal, EarlyView.
We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.

Chemotherapeutic Potential of Fluorouracil‐Platinum (IV) Prodrugs Against Cisplatin‐Resistant Colorectal Cancer Cells

Chemistry – A European Journal, EarlyView.
ABSTRACT Fluorouracil‐platinum(IV) prodrugs represent a novel class of multimechanistic chemotherapeutics with enhanced anticancer potential. The prodrugs PtIVP‐5FUMeOBut and PtIV56‐5FUMeOBut were actualized by derivatising the clinical drug 5‐fluorouracil (5FU) and coordinating it to platinum(IV) complexes, leveraging the established cytotoxicity of ...

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.
