  摘要：

  Indium-mediated allylation of N-Cbz-L-prolinal 3, under Grignard conditions, was carried out with high yield and stereoselectivity (de = 90%) to afford intermediate (2S, 1'R)-N-benzyloxycarbonyl-2-(1'-hydroxybut-3'-en-1'-yl)pyrrolidine 4, which was transformed in two steps into (1R,3R,7aS)-1-hydroxy-3-hydroxymethylpyrrolizidine 9. Commercial Cbz-L-proline was a source of functionalization and chirality. (c) 2005 Elsevier Ltd. All rights reserved.

  Ligands, and Targets Abstract A simple and convenient method for the synthesis of bis-functionalised pyrrolizidines starting from readily available N-Cbz-l-prolinal is described. This aldehyde was converted within two concise steps to the corresponding aminoepoxides, which were separately subjected to regioselective cyclisation induced by a reductive cleavage of the Cbz protecting group. The versatile
