Synthesis of peptidomimetics using a polymer-bound Boc-linker
Thomas Redemann, Holger Bandel, GŁnther Jung
Boc-resin-bound a-hydroxy-b-amino-aldehydes are accessible starting from N-terminally bound amino acid esters by using Dondoni's C_1-homologation reaction sequence. The conversion of these synthons to two different peptide mimetics - 2-hydroxy-1,3-ethyl-diamines and g-hydroxy-d-amino-vinyl sulfones - has been investigated. The successful transfer of the complex a-amino acid homologation reaction sequence into solid-phase chemistry demonstrates the potentials of the Boc-resin for synthesis of peptidomimetics.
