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

Angewandte Chemie International Edition, Volume 65, Issue 37, 7 September 2026.
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 ...

A Novel Class of “Super‐Strained” Spiro Heterocycles: Gateway to 1‐Azaspiro[3.3]heptane Derivatives, and Biological Validation

Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.
A new class of “super‐strained” spiro heterocycles—spirocyclic 1‐azabicyclo[1.1.0]butanes—was synthesized via insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into substituted azirines. The stability of this new class of compounds was studied.

Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation

Advanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.

Selective Photoinduced α‐Amino C(sp3)–H Alkylation Mediated by NHC–Borane

Advanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
Herein, we report a selective photoinduced functionalization of α‐amino C(sp3)─H bonds mediated by NHC–boranes. This reaction proceeds efficiently without the need for any external radical initiator or photoredox catalyst. Mechanistic studies reveal that the reaction proceeds via an efficient radical chain, featuring the formation of an aryl radical ...
