preparation of C-terminal peptide α-ketoacids is described. Loading this linker on the solid support allows preparation of side-chain unprotected peptide cyanosulfurylides, which are easily oxidized to generate the corresponding C-terminal peptide α-ketoacids. The peptide α-ketoacids serve as protease inhibitors as well as segments for proteinsynthesis with the α-ketoacid–hydroxylamine (KAHA) amide-forming

A new cyanosulfur-ylide based linker makes possible the synthesis of C-terminal peptide α-ketoacids by solidphase synthesis. The preparation of the requisite linker and its application to a variety of C-terminal peptide α-ketoacids with unprotected side chains is reported.
