Formation of Bicyclic Skeletons by Aerobic, Manganese‐Mediated Cyclization of β‐Oxoesters

European Journal of Organic Chemistry, Volume 29, Issue 30, 12 August 2026.
Manganese(III) promotes aerobic radical cyclization reactions of β‐oxoesters with an ω‐alkenyl side chain at the β’‐position to give bicyclic products with a 1,4‐dicarbonyl structure. Bicyclic perhydro‐pentalene, ‐indene, and ‐azulene, as well as decaline skeletons were accessed by aerobic manganese(III)‐mediated radical cyclizations of cyclic β ...

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

Chemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.
