  • Title: Enantioselective total syntheses of belactosin A, belactosin C, and its homoanalogue.
    Author: Larionov OV, de Meijere A.
    Journal: Org Lett; 2004 Jun 24; 6(13):2153-6. PubMed ID: 15200308.
    Abstract:
    [reaction: see text] Enantioselective total syntheses of belactosin A, belactosin C, and its homoanalogue have been accomplished in high overall yields (32% for belactosin A from the amino acid 10, and 35 and 36% for belactosin C and its homoanalogue, respectively). This concise approach comprises a novel sequential acylation/beta-lactonization reaction and allows a facile alteration of the substituents, thus providing a flexible route to a new family of highly active belactosin-based proteasome inhibitors.
