NIR‐Activatable, Sequence‐Specific Metal‐Nucleic Acid Scaffolds for Responsive Uncaging
Angewandte Chemie, EarlyView.We demonstrate that long‐range nucleic acid‐mediated electron transfer can drive Pt(IV) photoreduction, establishing a new class of metal‐nucleic acid scaffolds capable of “responsive uncaging,” where hybridization with target DNA or miRNA directly triggers payload release under NIR irradiation.

Control of Tetrazine Bioorthogonal Reactivity by Rotaxanation
Angewandte Chemie, EarlyView.Control of tetrazine‐mediated inverse electron demand Diels–Alder (IEDDA) reaction has been achieved by rotaxanation. Tetrazine rotaxanes were synthesized in high yield and they displayed a much slower kinetics compared to the corresponding thread. Mechanical bond disassembly upon the right stimulus activates reactivity.

Angewandte Chemie, EarlyView.Catalysts based on earth abundant cobalt {as cationic [LCoI]+} and readily available ligands are practical alternatives to prohibitively expensive Rh‐catalysts for intramolecular [4+2]‐cycloadditions of 1,3‐diene‐8‐ynes and 1,3‐diene‐8‐enes. Tunable phosphino‐oxazoline ligands enable an alternate intramolecular [2+2]‐cycloaddition mode in 1,3‐diene ...

Angewandte Chemie, EarlyView.An electrochemical α‐C─H functionalization of nitramines enables the synthesis of molecules containing bifunctional energetic heterocycles with promising properties. A telescoped, HNO3‐free sequence involving nitration and azolation steps offers a safer, modular, and scalable platform for the synthesis of energetic compounds.
