Synthesis of (R)-(+)-Boc-Iturinic Acid (n-C14) from Aspartic Acid
摘要:
The first enantiospecific synthesis of the n-C14 isomer of iturinic acid, suitably protected for peptide synthesis, is presented. A new method for the synthesis of enantiomerically pure beta-amino acids from aspartic acid is used. The key step consists of an organocuprate addition to a tosylate derivative of aspartic acid, reduced at the alpha-carboxylic acid.
