A Method for the Preparation of Stereochemically Defined ψ Pseudodipeptides
TenBrink, Ruth E.
, p. 418 - 422 (1987)
A short, stereochemically defined synthesis of (2S,5S)-ψ pseudodipeptides (7a,7b,10) using commercially available, chiral amino acids has been developed.The key step of the synthesis is the intramolecular SN2 displacement of bromine with alkoxide to give 1,4-oxazin-2-ones (6a,6b,9) that are subsequently hydrolyzed to the desired ψ pseudodipeptides.
