Dearomatization with Axial‐to‐Central Chirality Conversion

European Journal of Organic Chemistry, Volume 29, Issue 17, 5 May 2026.
Atropisomers are exciting synthetic targets with unique properties, which find applications in many fields of chemistry. However, considering them as substrates is not very frequent, notably in the context of dearomatization reaction. We wish to discuss the different strategies for the dearomatization of aromatic atropisomers with axial‐to‐central ...

Spectroscopy and Conformer‐Selective Photoelectron Circular Dichroism of Chiral Molecules

Chemistry – An Asian Journal, Volume 21, Issue 9, 14 May 2026.
Photoelectron circular dichroism (PECD) is a forward–backward asymmetry in the angular distribution of the electrons emitted by a chiral molecule ionized by a circularly polarized light (CPL). Its sensitivity to conformation is studied by one‐photon or resonance‐enhanced two‐photon ionization, the latter being conformer‐selective.

Mix‐to‐Prepare Dicarboxylic Acid‐Based Decoy Molecules Enable Wild‐Type P450BM3‐Catalyzed Oxidation of Non‐Native Substrates

ChemCatChem, Volume 18, Issue 9, 14 May 2026.
Amic acid‐based decoy molecules were developed by simple mixing of acid anhydrides and amines. The newly identified phthalic acid‐based decoy molecules enabled whole‐cell benzene hydroxylation by cytochrome P450BM3, achieving phenol production about 3 mM, without the need for prior complex chemical synthesis and purification of the decoy molecules ...

Probing Electronic Effects Upon Nucleophilicity and Lewis Basicity of Isothiourea HyperBTM Catalyst Derivatives

ChemistryEurope, Volume 4, Issue 5, May 2026.
Systematic variation of the position and electronic effect of substituents within the benzannulated aromatic part of the HyperBTM catalyst framework indicates that catalysts containing electron‐donating substituents outperform their electron‐deficient variants in terms of rate and enantioselectivity in acylation reactions.
