Passerini Reaction−Amine Deprotection−Acyl Migration Peptide Assembly: Efficient Formal Synthesis of Cyclotheonamide C
摘要:
A short, convergent, formal total synthesis of cyclotheonamide C Is described. The key linear pentapeptide Intermediate is assembled at the same time as the elaboration of the alpha-hydroxyhomoarginine (H-hArg) residue via a three-component Passerini reaction-amine deprotection-O,N-acyl migration strategy.
