Rh‐Catalyzed [2 + 2 + 2] Cycloaddition of Linked Bis(Diynes) Ar‐C≡C‐C≡C‐(CH2)3‐C≡C‐C≡C‐Ar With Quinones: Synthesis and Photophysical Properties of Bis(Arylethynyl)‐Naphthoquinones and Anthraquinones

Chemistry – A European Journal, Volume 32, Issue 11, 16 March 2026.
We report the synthesis bis(arylethynyl)naphtho‐ and anthraquinones via Rh(I)‐catalyzed [2 + 2 + 2] cycloaddition reactions. The substrate scope of both quinones and linked bis‐diynes was explored. Microwave irradiation remarkably enhanced yields.

A General Group Testing Strategy for Discovering Chemical Cooperativity

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
A combinatorial design theory‐based group testing strategy coupled with luminescence screening to uncover cooperative interactions in a large combinatorial space. Iterative deconvolution identifies reactive molecular pairs and enables the discovery of trifluoromethylthiolation (SCF3) reagents.

Combination of a UPO‐Based Epoxidation With a Subsequent Ring‐Opening Reaction for the Synthesis of Amino Alcohols

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
The synthesis of aromatic amino alcohols via a combination of an unspecific peroxygenase‐catalysed reaction, oxyfunctionalization, and addition of selected nucleophiles and electrophiles in a highly atom‐efficient manner was investigated. This study presents the design to aim for an atom‐efficient chemo‐enzymatic synthesis route towards aromatic amino ...

Pyridine Into Pyrrole Transformation Induced Within the Confinement of the Macrocycle

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
This work demonstrates the nontrivial reactivity of pyridine incorporated into a porphyrin framework. The most significant achievement is the contraction of the six‐membered ring to a pyrrole ring, which is a phenomenon of great interest to researchers in this field.
