Building Functionalized Peptidomimetics: Use of Electroauxiliaries for Introducing N-Acyliminium Ions into Peptides
摘要:
A series of silyl-substituted amino acids have been synthesized, inserted into peptides, and then employed as precursors for oxidatively generating reactive N-acyliminium ions. Both electrochemical and chemical oxidation procedures have been employed. N-Acyliminium ion generation in a solid-phase substrate as well as application to a small library of functionalized dipeptides has been demonstrated. Limitations in terms of how electron-rich the silyl groups can be as well as the compatibility of multiple silyl groups within a longer peptide are defined.

[reaction: see text]. Silylated aminoacids have been incorporated into peptides and then converted into N-acyliminium ions with the use of an anodic oxidation reaction. The result is a method for selectively incorporating conformational constraints or external nucleophiles within the peptide.
