Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling

Angewandte Chemie International Edition, EarlyView.
Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

Three-component N-alkenylation of azoles with alkynes and iodine(III) electrophile: synthesis of multisubstituted N-vinylazoles

Beilstein Journal of Organic Chemistry
A stereoselective N-alkenylation of azoles with alkynes and iodine(III) electrophile is reported. The reaction between various azoles and internal alkynes is mediated by benziodoxole triflate as the electrophile in a trans-fashion, affording azole ...

Mapping the Reactivity of the C═C Bond of Cyclic Enol Ether Derivatives of Sugars: Nucleophilicity Parameters of Glycals

Angewandte Chemie International Edition, EarlyView.
Endo or Exo? The first quantitative kinetic mapping of the nucleophilic reactivity of endo‐ and exo‐glycal compounds highlighted that endo‐glycals are typically 102 times less reactive than their corresponding parent cyclic enol ethers while exo‐glycals are 103 more nucleophilic. This experimental and computational structure–reactivity study highlights

Radical Cascade Combining Cross‐Olefin Coupling with the Smiles‐Truce Rearrangement

Angewandte Chemie International Edition, EarlyView.
We present a cobalt‐catalysed radical cascade that efficiently merges two alkene starting materials to form multiple bonds in a single step. The process begins with a cobalt‐catalysed hydrogen‐atom transfer‐to a styrene double bond, followed by a Giese addition.
