Chemoselectivity and Enantioselectivity in the Conjugate Reduction of Cinnamate Esters and a Tandem Conjugate Reduction‐Ester Hydrogenation Using Manganese Catalysts

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
An improved synthesis of a manganese catalyst used for hydrogenation of ketones, esters and imines is reported. The catalyst has now been found to effect tandem conjugate reduction‐ester hydrogenations with very low amounts of allylic alcohol by‐products.

Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

Elevating Haloperoxidase Expression in Escherichia coli through Fusion with a Formate Oxidase

ChemBioChem, Volume 27, Issue 7, 14 April 2026.
Fusing Aspergillus oryzae formate oxidase (AoFOx) to Curvularia inaequalis vanadium chloroperoxidase (CiVCPO) boosts soluble expression and enables formate‐driven, in situ H2O2 supply for halogenation. Screening linker/orientation variants delivered up to 9‐fold higher haloperoxidase activity in E.

From Mechanisms to Materials: Oximate Reactivity and Emerging Strategies for Organophosphate Detoxification

ChemPhysChem, Volume 27, Issue 7, 14 April 2026.
The development of effective strategies for the detoxification of organophosphorus (OP) nerve agents has evolved from the early mechanistic studies of François Terrier and collaborators, who first elucidated the exceptional nucleophilicity of α‐effect species such as oximes and hydroxamates, to the modern design of supramolecular and material‐based ...
