Fungal Isocyanide Synthases and Xanthocillin Biosynthesis in Aspergillus fumigatus

mBio, 2018
Microbial secondary metabolites, including isocyanide moieties, have been extensively mined for their repertoire of bioactive properties. Although the first naturally occurring isocyanide (xanthocillin) was isolated from the fungus Penicillium notatum ...

Synthesis of β‐ and γ‐Carbolinones Through a Fe(III)‐Mediated Radical 6‐Endo‐Trig Cyclization of Indole‐Based Ugi 4‐CR Adducts

European Journal of Organic Chemistry, EarlyView.
A practical strategy for synthesizing β‐ and γ‐carbolinones from indole‐based Ugi 4‐CR adducts through an intramolecular radical cyclization using Fe(III)–H species is presented. This approach enables the efficient synthesis of spiro‐carbolinones under mild reaction conditions and demonstrates the effectiveness of secondary radicals in both cyclization

Counterion Effects in Decatungstate Photocatalysis

European Journal of Organic Chemistry, EarlyView.
Decatungstate photocatalysis is often discussed from an anion‐centered perspective, treating the counterion as a passive charge‐balancing species. This review highlights that counterion identity can instead profoundly influence catalyst solubility, ion pairing, aggregation, stability, substrate accessibility, and catalytic performance.

An NHC‐Coordinated Silicon/Sulfur Analogue of an Acyl Carbene

Angewandte Chemie, Volume 138, Issue 35, 24 August 2026.
An NHC complex of an Si/S analogue of an acyl carbene is synthesized by the reaction of a disilyne with a cyclic thiourea. The observed Si2S three‐membered ring with unsymmetrical Si─S distances and a Si─Si single bond is consistent with intramolecular coordination of the silathioacyl sulfur to the silylene center.

FeIII‐Mediated Synthesis of Azaspirodienones via Ipso‐Radical Cyclization of Ugi–4CR Adducts

European Journal of Organic Chemistry, EarlyView.
An efficient two‐step protocol for the synthesis of azaspirodienones via Fe‐mediated ipso‐radical cyclization of Ugi adducts has been developed. This methodology provides rapid access to these privileged spirocyclic architectures under mild conditions, offering a practical and versatile approach to generating structurally complex molecules with ...

Exploring a Ugi‐Mediated Polymerization‐Induced Self‐Assembly Approach to Peptoid Particles

Macromolecular Rapid Communications, EarlyView.
Ugi‐mediated polymerization‐induced self‐assembly (U‐PISA) enables the one‐pot synthesis of PEG‐stabilized polypeptoid nanoparticles under mild aqueous conditions. By tuning PEG molar mass and feed composition, tunable spherical and worm‐like nano‐objects are obtained.
