From beginning to end: the synecology of tree‐killing bark beetles, fungi, and trees
ABSTRACT Over a century of research has revealed an amazing complexity of behaviours and physiological adaptations that allow tiny bark beetles to overcome large trees, sometimes resulting in outbreaks that kill millions of trees. Turning a tree into a home and successfully raising offspring involves constant interactions among the beetles, the tree ...

Programmable Microwaveable Chemistry in the Chemputer
The Chemputer integrates complementary microwave modules under χDL control, enabling fully automated syntheses of O‐alkylation products, Suzuki–Miyaura cross‐couplings, ring‐closing metathesis, and peptide sequences via solid‐phase methods. This modular, programmable platform delivers flexible and scalable microwave‐assisted workflows, broadening ...

Thiophene Derivatives as Versatile Precursors for (Hetero)Arene and Natural Product Synthesis
Hidden but Powerful: Thiophenes and their saturated analogues have been demonstrated to be versatile C4‐building blocks that can be rapidly applied to natural product synthesis and the construction of functionalized (hetero)arenes. This minireview aims to provide a concise overview of the strategies and implementations of these sulfur‐containing ...

Photocatalyzed Ring Expansion of α‐Ketosulfonylaziridines: Ready Access to δ‐Sultams
A novel radical–polar crossover (RPC) photoredox‐catalyzed reaction for the synthesis of δ‐sultams from N‐sulfonyl α‐ketoaziridines through a controlled ring opening–expansion process is presented. This method allows the easy access to sultams with an unprecedented substitution pattern in up to 85% yield and 2:1 d.r., and highlights the potential of ...

18F‐Radiopharmaceutical Diversification Enabled by Deaminative Cross‐Electrophile Couplings
A general Ni‐mediated (C)sp2–(C)sp3 cross‐coupling expedites access to 18F‐radiopharmaceuticals, essential for positron emission tomography imaging and drug discovery. This late‐stage diversification approach was implemented across three user‐friendly automated protocols affording 18F‐radiotracers in sufficient quantities for imaging.
