摘要

The condensation of ketones and hydroxylamines to form ketonitrones was reinvestigated by using thermal conditions previously found to minimize hydroxylamine decomposition (t- BuOH, 110° C). This simple approach allows the formation of exocyclic, acyclic, and α, β- unsaturated ketonitrones with benzylic, linear, and branched nitrogen substituents in modest to excellent isolated yields.
