  Synthesis of Anisolylated Aspartyl and Glutamyl Tripeptides

  摘要：

  A process has been developed for transforming the beta-carboxyl of aspartate and the gamma-carboxyl of glutamate into anisolyl ketones. These ketones are occasional byproducts in peptide synthesis, resulting from deprotection or resin-removal processes in the presence of anisole as a scavenger. The ketone amino acids have been incorporated in a tripeptide by coupling with CBMIT. During peptide bond formation-the keto group of the glutamyl residue required protection, which was provided as the ethylene dithioketal.
