ChemElectroChem, Volume 13, Issue 12, 17 June 2026.Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Prins fluorination cyclisations: Preparation of 4-fluoro-pyran and -piperidine heterocycles
Beilstein Journal of Organic Chemistry, 2010 The Prins reaction was investigated using BF3·OEt2 as a Lewis acid. It has been recently demonstrated, that if BF3·OEt2 is used in stoichiometric amounts then these reactions generate fluorinated products where the BF3·OEt2 contributes fluoride ion to ...

Recent Advances in Intramolecular C─N Bond Formation for Pyrrolidine Synthesis
ChemistryOpen, Volume 15, Issue 6, June 2026.This review highlights synthetic advances (2013–2025) in intramolecular C─N bond formation for constructing the pharmaceutically relevant pyrrolidine core. The review is organized into five methodological clusters: 1) intramolecular alkene/alkyne amination; 2) tandem annulations, which involve C─N bond formation as the key step; 3) nucleophilic ...
