Swermilactones A and B: racemic xanthone–secoiridoid heterodimers from Swertia mileensis
Yao Du, Hao Li, Xiao-Yu Qi, Yuan-Liang Xu, Yan Liu, Xue-Mei Niu, Kai Guo & Sheng-Hong Li
Org. Biomol. Chem., 2025, 23, 3860-3864

“This research article describes the isolation and structural characterisation of swermilactones A and B from Swertia mileensis. Unlike most natural products, the swermilactones were shown not to be enantiomerically pure, but rather scalemic. The strength of this paper lies in the rigour not only to uncover the scalemic nature of the natural products, but also in giving a sound scientific explanation for their possible biosynthesis.”

Discovery of a plant-like tridomain bifunctional syn-abieta-7,13-diene synthase in Streptomyces
Caitlin A. McCadden, Diana P. Łomowska-Keehner, Tracy Qu, Jordan Nafie, Tyler A. Alsup & Jeffrey D. Rudolf
Org. Biomol. Chem., 2025, 23, 9845-9850

“Terpene synthases in bacteria usually exhibit a single so-called alpha-domain or a combination of beta and gamma-domains, while plant terpene synthases usually contain three domains (alpha-beta-gamma). The present paper not only reports about the occurrence of alpha-beta-gamma domain terpene synthases from bacteria, but also about the bioinformatic identification of additional interesting gene fusions, suggesting multifunctional bacterial enzymes to be characterised in future work.”

Nitrones as directing groups in transition metal-catalysed C–H activation
Barbara Stańska, Anjali Dahiya & Rafał Loska
Org. Biomol. Chem., 2026, 24, 11-37

“This review highlights the role of nitrones as directing groups in transition metal-catalysed C-H activations. C-H activations continue to be a hot topic, but the non-expert reader may not be aware that nitrones can play important roles in catalytic processes. This review article follows a highly didactic approach and also identifies important open questions such as the development of chiral catalysts for enantioselective reactions.”

Facile DNA chemical ligation under mild conditions enabled by 1-cyano-4-(dimethylamino)pyridinium tetrafluoroborate (CDAP)

Hiroki Yamada, Yasuaki Kimura, Hiroshi Abe & Junichiro Yamamoto

Org. Biomol. Chem., 2025, 23, 4866-4872

“This paper establishes a new, nonenzymatic approach for DNA ligation. The authors show that CDAP, 1-cyan-4-(dimethylamino)pyridinium tetrafluoroborate, can be used as an alternative to cyanogen bromide (CNBR) to join 3′-OH and 5′-phosphate termini when aligned on a DNA template strand. The CDAP reaction proceeds efficiently, without DNA deglycosylation or other side reactions that are induced by CNBr and can be done on ice. Such findings should have value for joining DNA strands in various contexts.”

Exploring nickel-catalyzed organochalcogen synthesis via cross-coupling of benzonitrile and alkyl chalcogenols with computational tools

Francisco A. Gómez-Mudarra, Gabriel Aullón & Jesús Jover

Org. Biomol. Chem., 2025, 23, 1673-1682

“This work investigates a distinctive nickel(0)-catalysed cross-coupling between benzonitrile and alkyl chalcogenols to form C–S, C–Se, and C–Te bonds. By outlining a classic oxidative addition–transmetalation–reductive elimination pathway that unusually engages the Ph–CN bond, the study proposes a general mechanistic platform extending beyond thioethers to their heavier chalcogen analogues. Through kinetic analysis and microkinetic simulations, the authors demonstrate that this strategy could expand synthetic access to organochalcogen compounds of biological and materials relevance while maintaining excellent functional group tolerance.”

Effect of strain and π-acidity on the catalytic efficiency of carbones in carbodiimide hydroboration

Max Schernikau & O. Maduka Ogba

Org. Biomol. Chem., 2025, 23, 9896-9907

“Using DFT calculations, this paper explores how structural and electronic factors govern the performance of zerovalent carbon-centred organocatalysts (carbones) in the hydroboration of carbodiimides. The authors reveal that cyclic carbodiphosphoranes outperform their acyclic analogues owing to superior substrate activation and more efficient hydride transfer, as mapped by distortion/interaction–activation strain analysis. The study fills key gaps in understanding catalyst design and reactivity, underscoring the growing promise of carbones as versatile organocatalysts for bond-forming transformations.”

Impact of charges on the hybridization kinetics and thermal stability of PNA duplexes

Miguel López-Tena & Nicolas Winssinger

Org. Biomol. Chem., 2024, 22, 5759-5767

“Peptide nucleic acids have a range of potential biomedical applications because they form duplexes with DNA and RNA that are more stable than DNA or RNA homoduplexes. López-Tena and Winssinger analyse how modifications of PNA structure at the γ-position impact hybridisation stability and kinetics, demonstrating that the higher stability of duplexes involving PNA results from slower dissociation kinetics rather than association kinetics (which are also slower relative to a DNA:DNA duplex). This improves our understanding of how to design molecular structures with specific function.”

Enhanced binding of methyl alkylammonium cations through preorganization of a water-soluble calix[4]pyrrole

Esteban Valencia & Pablo Ballester

Substituent effects of fluorinated bambusurils on their anion transport

Matúš Chvojka, Vladimír Šindelář & Hennie Valkenier

Org. Biomol. Chem., 2025, Advance Article

“In another example of supramolecular structure-activity analysis, Chovjka, Šindelář and Valkenier evaluate the anion transport properties of a small library of fluorinated bambusurils. Defining structure-activity relationships of these molecules is key to meeting the multiple criteria for effective ion transport in cells that will be required for application in treating chanellopathies e.g. cystic fibrosis. This paper demonstrates how small structural changes can have a large, and sometimes unanticipated, impact on function.”
