摘要：

The reduction of a diphenyl alpha -iminoketone with samarium diiodide has been studied. A fast two-electron transfer gives a samarium (Z)-enamidolate, which is protonated to afford an alpha -aminoketone or reacted with a variety of ketones to furnish pyrrole derivatives. Possible mechanisms are proposed. (C) 2001 Elsevier Science Ltd. All rights reserved.
