Integrated Transition Metal Catalysed Reactions: Synthesis of Polysubstituted 4-(Phenoxymethyl)-3-pyrrolines and Their Isomers by One-Pot Coupling of Propargylamines, Vinyl Sulfones (or Nitroalkenes) and Phenols
pyrrole-3-carboxylates and 3,4-disubstituted pyrrolidin-2-ones. The latter were prepared by means of an unprecedented rearrangement process involving hydrogenolysis of 2-aryl pyrrolidine-3-carboxylates, whereas the pyrrole carboxylates arose from aromatization of the corresponding pyrrolines.
