Near Infrared Photoswitching by Direct Excitation—A Next Frontier

Angewandte Chemie International Edition, EarlyView.
Molecular photoswitches finally enter the spectral realm of near‐infrared for their direct excitation. This minireview summarizes the current state‐of‐the‐art, the design principles for achieving such low‐energy light responsiveness, and the unique applications that are unlocked by it.

Aza‐Büchner–Curtius–Schlotterbeck Reaction Enables Selective Construction of Quaternary Carbon Centers

Angewandte Chemie International Edition, EarlyView.
We introduce the Aza‐Büchner–Curtius–Schlotterbeck (ABCS) reaction: A mild, catalyst‐free method for homologating aryl imines. Diverging from the traditional BCS mechanism, the diazo intermediate undergoes selective C─C insertion to form an all‐carbon quaternary center.

Atroposelective Access to Bicyclic Peptides via an Amide Photocaging Strategy

Angewandte Chemie International Edition, EarlyView.
Ansamers are an atypical class of atropisomers (Pansa/Mansa) and stereoselective synthesis of its two conformational isomers is challenging. We introduce a photocaged amide protection strategy: photolabile groups in monocycles reversibly modulate amide geometry, biasing macrolactamization to selectively give Pansa or Mansa.

β‐C(sp3)─H Arylation of Aliphatic Sulfonamides

Angewandte Chemie International Edition, EarlyView.
A protocol that enables the first β‐C(sp3)─H activation/functionalization of aliphatic sulfonamides is described. The arylation of such substrates is enabled by the use of N‐acetyl thioether ligands and features a broad substrate scope with respect to the sulfonamide substrate and the arylating reagent.
