  Synthesis of Hexa- and Pentasubstituted Diketopiperazines from Sterically Hindered Amino Acids

  摘要：

  Steric hindrance assists in the formation of hindered diketopiperazines using acyl-transfer coupling. In acyl-transfer coupling, the carboxylate of an unprotected N-alkylamino acid attacks an active ester to form a transient anhydride that undergoes an O,N acyl transfer to form a tertiary amide. If the active ester is part of an N-alkylamino acid it will form a diketopiperazine. It is demonstrated here that acyl-transfer coupling can assemble highly functionalized bis-peptides bearing a functional group on every monomer.

  Functionalized bis-peptides as well as other amide-containing compounds are obtained by acylation of hindered amines. The functionalized bis-peptides are useful as shape-programmable nanostructures that are immune to denaturation and that contain arrays of functional groups having designed catalytic, protein-binding and/or sensor capabilities.
