European Journal of Organic Chemistry, EarlyView.Triplet–triplet annihilation upconversion (TTA‐UC) performed inside supramolecular viscoelastic gels enables efficient CC and C–heteroatom coupling reactions under green LED irradiation in open‐air conditions. The gel network restricts oxygen diffusion, preserves triplet states, and allows aryl halide activation through upconverted excited states ...

A Short Total Synthesis of the Daucane Sesquiterpenoid Ferutinin
European Journal of Organic Chemistry, EarlyView.Only nine steps were required to access the bioactive daucane sesquiterpene ester ferutinin (1) from 3‐methyl‐2‐cyclopentenone (3) and allyl p‐tolyl sulfoxide. A one‐pot 1,4‐addition/aldol sequence was used to rapidly provide diene 2 (TBS = tert‐butyldimethylsilyl), ring‐closing metathesis of which followed by alkylation and acylation gave rise to the ...

Electrochemical Three‐Component Synthesis of Heteroaryl Sulfonates
European Journal of Organic Chemistry, EarlyView.An electrochemical, metal‐free three‐component strategy for direct C(sp2)─H sulfonation of electron‐rich heteroarenes using SO2 and alcohols is described. Utilizing inexpensive graphite electrodes and practical SO2 stock solutions under mild conditions, this method provides straightforward access to heteroaryl sulfonates from simple building blocks ...

Narrowband Macrocycles: A New Paradigm for High‐Color‐Purity Organic Light‐Emitting Diodes
FlexTech, EarlyView.This graphical abstract illustrates two key strategies for constructing macrocyclic multi‐resonance (MR) emitters for high‐performance OLEDs: (1) the covalent assembly of MR moieties onto macrocyclic scaffolds, and (2) the local multi‐resonance strategy within the macrocyclic backbone.
