ISSN 1433-7851 Full text not available from this repository.AbstractA highly stereoselective route to functionalized pyrrolidines from the metal catalyzed diverted N-H insertion of a range of diazocarbonyl compounds with β-aminoketone derivatives is described. A number of catalysts (rhodium(II) carboxylate dimers, copper(I) triflate and an iron(III)porphyrin) are shown to promote the process under mild conditions to give a wide range of highly substituted proline derivatives. The reaction starts with a metallocarbene N-H insertion but is diverted by an intermolecular aldol reaction.
