  Formation of Dihydropyridone- and Pyridone-Based Peptide Analogs through Aza-Annulation of β-Enamino Ester and Amide Substrates with α-Amido Acrylate Derivatives

  摘要：

  The aza-annulation of beta-enamino ester and amide substrates with the mixed anhydride of 2-acetamidoacrylic acid was used for the efficient construction of highly substituted alpha-acetamido delta-lactam products. With the alpha-acetamido substituent, lactam functionality, and gamma-carboxylate group, these delta-lactam products represent an interesting class of conformationally restricted dipeptide analogs. The framework of this lactam hub is structurally related to that of an alpha-amino acid coupled with a beta-amino acid. When alpha-amino esters derived from naturally occurring amino acids were used in the enamine formation step, subsequent aza-annulation led to branched peptide surrogates with two C-termini that extended from a common N-terminus. Oxidation of the aza-annulation products resulted in the generation of a planar system with peptide functionality radiating from the 1, 3, and 5 positions of the pyridone hub. Alternatively, pyridone products could be formed directly from the enamino amides by reaction with 2-phenyl-4-(ethoxymethylene)oxazolone. Subsequent hydrolysis of the acetamido and ester substituents of the N-benzylpyridones was selectively performed to access unique beta-amino acid products. Formation of the mixed anhydride of this acid, followed by amide bond formation with the ester of an alpha-amino acid, allowed extension of the peptide chain from the dihydropyridone structure.
