2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

open access: yesChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...

Pseudotetraivprolide aus Pseudomonas entomophila liefern Einblicke in die Biosynthese von Detoxin/Rimosamid‐ähnlichen Anti‐Antibiotika

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Pseudotetraivprolid ist ein neuer Akteur unter den Detoxin/Rimosamid‐ähnlichen Naturstoffen. Die Biosynthese erfordert FabD aus dem Primärstoffwechsel und einen PipDFG‐Komplex für die Acetylierung im letzten Schritt – wodurch schließlich die anti‐antibiotische Wirkung entsteht.

Pseudotetraivprolides from Pseudomonas entomophila Provide Insights into the Biosynthesis of Detoxin/Rimosamide‐Like Anti‐Antibiotics

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
Pseudotetraivprolide is a new player among the Detoxin/Rimosamide‐like natural products! Its biosynthesis requires FabD from primary metabolism and a PipDFG complex for final‐step acetylation – unlocking its anti‐antibotic activity. Abstract Novel variants of known natural product (NP) classes can provide valuable insights into their biosynthesis ...
