The Jekyll and Hyde Nature of Tetrazoles in Polymer Science: From Intrinsic Electronic Duality to Programmable Macromolecular Function

Angewandte Chemie International Edition, EarlyView.
Tetrazoles are reframed as substitution‐programmable heterocycles rather than static functional groups in polymer chemistry. By linking electronic identity to synthetic strategy and polymer architecture, this mini‐review establishes a design framework for translating tetrazole duality into predictable macromolecular function.

Anomeric Amide Enabled Divergent Synthesis of Unsymmetrical Ureas, Carbamates, Thioesters, and Amides From Aldehydes

Angewandte Chemie International Edition, EarlyView.
An anomeric amide‐enabled divergent aldehyde functionalization sequence provides one‐pot access to unsymmetrical ureas, carbamates, thiocarbamates, thioesters, and amides. Key to this transformation is the formation of N‐Boc‐hydroxamate intermediates, which serve as platforms for orthogonal activation via Lossen‐type rearrangements, single‐electron ...
