Application

  • Traceless Staudinger ligation reagent with borane protecting group.
  • The borane group stabilizes the phosphine against oxidation and can be easily removed with mild basic or acidic conditions to yield the active phosphine.
  • After reaction with an azide, the phosphine is eliminated in the presence of water to yield a native amide bond.
  • Used in the synthesis of cyclic peptides.
