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.

Enantioselective Miyaura Reaction by Desymmetrizing C(sp2)–B Cross‐Coupling of 1,1′‐Biaryl‐2,6‐diyl Bis(nonaflates)

Angewandte Chemie, EarlyView.
A desymmetrization strategy for an enantioselective Miyaura‐type C(sp2)–B cross‐coupling to access highly enantioenriched, axially chiral biaryl boronic esters is disclosed. The enantiomeric excess of the chiral monoborylated product after reductive elimination is further improved by a downstream kinetic resolution, thereby converting the minor ...

Electrochemical ⍺‐C─H Functionalization of Nitramines for Accessing Bifunctional Energetic Heterocycles

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.

Sequence‐Specific Installation of Aryl Groups in RNA via DNA‐Catalyst Conjugates

Angewandte Chemie, EarlyView.
DNA oligonucleotides carrying amine nucleophilic catalysts are employed to deliver aryl groups to complementary sites in RNA under physiological conditions. The strategy can be used to sequence‐specifically label protein‐coding RNAs, or to knock down expression selectively, with potential applications in basic transcriptome research and in future ...
