  Stereoselective Synthesis of Pseudopeptide Microbial Agent AI-77-B

  摘要：

  [GRAPHICS]An efficient and highly stereoselective synthesis of the gastroprotective natural product Al-77-B is described. The stereocenters of the hydroxy amino acid moiety were generated by an ester-derived titanium-enolate-mediated syn-aldol reaction, a Curtius rearrangement, and application of Dondoni's aldehyde homologation. Condensation with the dihydroisocoumarin fragment and subsequent deprotecting transformations furnished optically active Al-77-B.
