  SN2'-Reactions of Peptide Aziridines. A Cuprate-Based Approach to (E)-Alkene Isosteres

  摘要：

  Alkenylaziridines were prepared from allylic alcohols via Sharpless epoxidation; oxirane to aziridine conversion under modified Staudinger conditions, and Wittig chain extension. Alternatively, beta-hydroxy alpha-amino acids such as threonine can serve as readily available precursors. The corresponding N-acyl, -peptidyl-, -carbamoyl-, and -sulfonylaziridines underwent a high-yielding anti-S(N)2' alkylation with organocopper/BF3 complex to give (E)-alkene peptide isosteres in 62 to >98% de. The stereoselectivity of the addition process was studied by H-1 and F-19 NMR as well as chemical degradation. Alkene isosteres are important nonhydrolyzable and rigidified analogs of peptide bonds in biologically active peptides. This new methodology considerably facilitates the synthesis and the study of these peptide mimetics, since alkenylaziridines are readily prepared and side-chain modification is simplified by the wide range of functionalized organocopper reagents that are available.
