Electron Donor–Acceptor Complexes Without Preinstalled Sacrificial Leaving Groups: Applications in Synthesis

Helvetica Chimica Acta, EarlyView.
Leaving‐group–free electron donor–acceptor (EDA) complexes have emerged as a practical platform for photocatalyst‐free radical generation under visible light. This review highlights recent advances in coupling and cyclization reactions driven by such EDA complexes, emphasizing their atom‐economical and sustainable feature.

Transannular O‐Heterocyclization Reactions of Cyclododeca‐1,5,9‐triene Derivatives: A New Concept for the Preparation of Key Intermediates for Total Syntheses of Annonaceous Acetogenins

Helvetica Chimica Acta, EarlyView.
Four stereogenic centers are formed diastereoselectively in one step from a cyclic (E,E)‐1,5‐diene system using an electrophilic addition reaction. Subsequent ozonolytic cleavage of the intact Z‐double bond, followed by intramolecular nucleophilic substitution, yields an octahydroterfurandione with a threo,cis,threo configuration, an arrangement found ...

Phosphoramidate and Silyl Amine Mediated Synthesis of Isocyanide Cyclopentadienone Iron Complexes

Helvetica Chimica Acta, EarlyView.
Carbonyl ligands in cyclopentadienone iron complexes are replaced by isocyanide ligands without using free, malodorous isocyanides. The reaction takes place via an Aza‐Wittig‐type reaction starting from primary amines, employing either phosphoramidates or silyl amines as intermediate reagents.
