Formation of oxazolines and thiazolines in peptides by the mitsunobu reaction
摘要:
The Mitsunobu reaction was efficiently used to introduce oxazolines and thiazolines in the peptide backbone. The reaction proceeded from beta-hydroxy alpha-amino acid-containing peptides at room temperature in 58-72% isolated yields.

The stereospecific dehydration of threo-N-acyl-beta-hydroxy-alpha-amino acid derivatives was performed using Martin's sulfurane to give (Z)-alpha,beta-dehydroaimino acids, while erythro-N-acyl-beta-hydroxy-alpha-amino acid amides were converted to 4,5 transoxazolines using analogous reaction conditions.
