  A β,β′-ketoaminoester as a valuable tool for the asymmetric construction of substituted homopipecolic esters: application to a formal synthesis of (+)-Calvine

  摘要：

  A highly diastereoselective 1,4-addition involving Davies' lithium amide is employed as the key reaction to prepare, in five steps from ethyl acetoacetate, an enantiomerically pure keto protected beta,beta'-ketoaminoester. This latter was reacted with aldehydes in an intramolecular Mannich process and furnished a direct and stereoselective access to substituted homopipecolates. The validity of this approach was achieved through a new formal asymmetric synthesis of alkaloid (+)-Calvine. (C) 2004 Elsevier Ltd. All rights reserved.
