  Direct Entry to Peptidyl Ketones via SmI₂-Mediated C−C Bond Formation with Readily Accessible N-Peptidyl Oxazolidinones

  摘要：

  [GRAPHICS]In this work, a new method for the preparation of peptidyl ketones is presented employing a SmI2/H2O-mediated coupling of N-peptidyl oxazolidinones with electron-deficient alkenes. The requisite peptide imides were easily prepared by solution-phase peptide synthesis starting from an N-acyl oxazolidinone derivative of an amino acid. Importantly, they could be used directly in the C-C bond-forming step without the need for further functionalization. Coupling of these peptide derivatives with a second peptide possessing an N-terminal acryloyl group leads to ketomethylene isosteres of glycine-containing peptides. This method represents an alternative means for ligating two small peptides through a C-C bond-forming step.
