Navigating the Radical Oxo‐Functionalization of Alkenes Toward Ketones
European Journal of Organic Chemistry, EarlyView.Straightforward access to complex ketones in a single synthetic step: This Review surveys the latest advances in three‐component alkene 1,2‐oxo‐functionalizations. The opportunities unlocked by the so‐called single‐electron (1e–) logic, including access to a broad pool of radical precursors and carbonyl oxygen atom sources, are highlighted.

Efficient Synthesis of Cannabinoid Acids
European Journal of Organic Chemistry, EarlyView.In this study, an alternative synthesis of cannabinoid acids was developed based on an O→C acyl rearrangement. Specifically, this strategy involved regioselective bromination followed by halogen–lithium exchange and intramolecular nucleophilic addition, which led to successful carboxylation.

Fluorinated Iminosugar Glycomimetics: Synthesis and Activity as GCase Ligands
European Journal of Organic Chemistry, EarlyView.DAST‐mediated deoxyfluorination of suitably functionalized piperidines provided regio‐ and stereoselective access to fluorinated piperidine and pyrrolidine glycomimetics, the latter arising from an unusual ring‐contraction process. Fluorination generally enhanced β‐glucocerebrosidase (GCase) inhibitory potency, but lost PC activity toward L444P/L444P ...

Photocatalysis‐Triggered Click Reactions and Applications
European Journal of Organic Chemistry, EarlyView.Photoclick chemistry offers broad applications ranging from materials science to bioconjugation, with precise spatiotemporal control over click reactions. Initially limited to UV activation, recent advances have extended photoclick processes to the visible and NIR regions thanks to the photocatalysis.

European Journal of Organic Chemistry, EarlyView.Deprotonation of chiral α‐silyl secondary alcohols leads to masked polarity‐reversed chiral carbanions through stereospecific 1,2‐Brook rearrangement. In situ trapping with Weinreb amide electrophiles affords α‐hydroxyketones with moderate to excellent enantiospecificity (es).

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers
FlexMat, EarlyView.Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...
