  The asymmetric synthesis of (2 S ,3 R )-capreomycidine

  摘要：

  An improved asymmetric synthesis of the guanidine-containing amino acid (2S,3R)-capreomycidine has been achieved in seven steps and 28% overall yield. The key synthetic step involved a Mannich-type reaction between a chiral glycine aluminum enolate and the benzyl-imine of 3-tert-butyldimethylsiloxy-propionaldehyde. (C) 2001 Elsevier Science Ltd.

• Asymmetric Synthesis of (2<i>S</i>,3<i>R</i>)-Capreomycidine and the Total Synthesis of Capreomycin IB
  作者：Duane E. DeMong、Robert M. Williams

  DOI：10.1021/ja0351241

  日期：2003.7.1

  A 27 step total synthesis of the tuberculostatic macrocyclic peptide antibiotic capreomycin 113 has been accomplished. The synthesis features the use of an enolate-aldimine condensation between a chiral glycine aluminum enolate and the benzyl imine of 3-tert-butyldimethylsiloxy-propanal as a means of preparing the cyclic guanidine amino acid (2S,3R)-capreomycidine. Additionally, a Hofmann rearrangement was exacted on a late-stage pentapeptide in order to transform an asparagine residue into a diaminopropanoic acid residue.
