An unexpected transformation by reduction of isoxazolines
Comptes Rendus. Chimie, 2012 Abstract Aromatic nitrile oxides undergo regio- and stereo-specific 1,3-dipolar cycloaddition reactions with racemic 5-hydroxy-4-methyl-1,5-dihydropyrrol-2-one derivatives 1 . In each case, a single product 3 results from an anti approach to the hydroxyl group, the oxygen of the 1,3-dipole being attached to C-5 of pyrrolidinones.

Advanced Science, Volume 12, Issue 15, April 17, 2025.A nitrogen‐doped carbon nitride (NCN) has been synthesized and applied for the sustainable generation of reactive nitrogen and oxygen radicals. The NCN catalyst facilitates radical carboamination, oxyamination, and deoxygenation reactions, as well as the oxidation of boronic acids and alcohols, all under mild photocatalytic conditions.

European Journal of Organic Chemistry, Volume 28, Issue 12, March 24, 2025.A dehydrogenative photoredox catalyzed formal C(sp3)‐H intramolecular cyclization of indolyl‐oximes to generate indolyl Δ2‐isoxazolines is reported. In contrast to the current state‐of‐the‐art, the reaction avoids the use of super stoichiometric chemical oxidants and high reaction temperatures and is proposed to operate via two sequential single ...
