White, Nicholas A.; Rovis, Tomislav published the artcile< Oxidatively Initiated NHC-Catalyzed Enantioselective Synthesis of 3,4-Disubstituted Cyclopentanones from Enals>, Formula: C9H7BrO, the main research area is NHC catalyst oxidative enantioselective cyclization aryl enal; cyclopentanone stereoselective preparation.
An unprecedented N-heterocyclic carbene (NHC)-catalyzed annulation of enals to form 3,4-disubstituted cyclopentanones, e.g. I, has been discovered. Aryl enals undergo dimerization in the presence of a single-electron oxidant to form C2 sym. cyclopentanones. A cross-reaction has also been developed, allowing for the synthesis of differentially substituted cyclopentanones. Mechanistically, the reaction is thought to proceed through radical intermediates, further establishing the synthetic utility of this class of reactivity.
Journal of the American Chemical Society published new progress about Enantioselective synthesis. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Formula: C9H7BrO.
