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 N N bond formation reaction. These catalytic reactions proceed in excellent yields with a broad scope.

A new strategy for highly diastereoselective synthesis of furo[3,2-b]-β-lactams and furo[3,2-b]-γ-lactams via a novel Ag(i)-mediated intramolecular 1,3-dipolar cycloaddition of oxo-N- propargylamides, is developed and the possible mechanism of these trans
