  Enantioselective synthesis of β-amino-diacids

  摘要：

  An efficient route to orthogonally protected beta-amino-diacids is described: chiral derivative 3 was shown to be a precursor of enantiopure substituted beta-amino acids. The key step of the procedure is a diastereoselective reduction of beta-enaminolactones 5 by NaBH3CN in CH2Cl2. A study concerning the regio- and diastereoselectivity of alkylation of beta-enarninolactone 3 is also presented. (c) 2005 Elsevier Ltd. All rights reserved.
