Modular and Stereoselective Synthesis of Cyclobutane β‐Amino Alcohols

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
Late‐stage functionalization and photoisomerization of 1,2‐azaborine leads to a general strategy for the synthesis of diversely substituted cyclobutane β‐amino alcohols. The relative stereochemistry of the resulting products is unambiguously defined by the stereospecific and stereoselective nature of the photoisomerization‐hydrogenation‐oxidation ...

Orchestrating Anion–π+ Interactions to Accelerate Metal‐Free Room‐Temperature Phosphorescence

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
Tuning anion–π+ interactions in pyridinium iodide contact ion pairs enables ultrafast metal‐free room‐temperature phosphorescence (540–605 nm) with radiative rates up to 5.2×105 s−1. Strong iodide→π+ charge‐transfer coupling, enhanced spin–orbit interactions, and dynamic ion‐pair organization accelerate intersystem crossing and emission, establishing ...

Ni2‐Imido Bispincer Platforms: Cooperative Reactivity Enabled Through Substrate Addition Across a Ni2N Unit

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Ni2 bispincer complexes with an embedded central imido anchor are presented. The bispincer complexes leverage the high basicity of imido ligands to facilitate 1,2 addition of weak B─H and Si─H bonds, resulting in hydrido–amido complexes and resultingly a contortion of a Ni─Ni sigma bond to form an S = 1 species. The 1,2 addition is proposed to serve as

Intramolecular Nickel‐Catalyzed Reductive Coupling: Enantioselective Synthesis of Tetrahydroisoquinolines and Related Heterocycles

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
The successful extension of the nickel‐catalyzed asymmetric coupling of polarized 1,3‐dienes with aldehydes to an intramolecular setting opens an efficient new entry into hydroxylated N‐heterocyclic compounds, most notably valuable tetrahydroisoquinolines.

Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

European Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...
