- Abstract
A convenient copper-catalyzed approach has been developed for the synthesis of substituted spiro-fused pyrazolin-5-ones from readily available cyclopropyl O-acyl ketoximes via an intramolecular NN bond formation reaction. These catalytic reactions proceed in excellent yields with a broad scope.
