## Oxidation of Hydroxylamines to Nitrones Catalyzed by (Salen)Mn(III) Complexes. Enantioselective Synthesis of a Protected cis-Dihydroxypyrroline N-Oxide with Jacobsen Catalyst. -The Jacobsen salen catalyst is found to catalyze efficiently the oxidation of N,N-disubstituted hydroxylamines (I) t
I) and addition of nitrones (II) results in a smooth condensation to give the unsaturated hydroxylamines (III) stereoselectively. These undergo reverse-Cope cyclizations at room temperature leading to the diastereomeric mixture of pyrrolidine-N-oxides (IV) and (V). -
