The stereospecific dehydration of threo-N-acyl-β-hydroxy-α-amino acid derivatives was performed using Martin's sulfurane to give (Z)-α,β-dehydroamino acids, while erythro-N-acyl-β-hydroxy-α-amino acid amides were converted to 4,5-trans-oxazolines using an

The enzymatic hydrolysis of N-protected dehydrodipeptide methyl esters (2) (Protect-ΔAA-AA-OMe) was first achieved, despite the requisite of the only neutral and large proteinic L-α-amino acid (AA) in the case using papain. Furthermore, the reverse enzymatic coupling of the C-component 2 with N-component α-amino acid anilides or dehydrodipeptide esters containing dehydrovaline (ΔVal) residue was also successful. Consequently, the present study suggests that the proteolytic enzyme papain is able to become a very useful tool for peptide synthesis by a coupling of the C-component dehydropeptide with N-component α-amino acid, peptide, or dehydropeptide.
