Résumé
The compounds such as 3-(1-(benzyloxy)-3-(ethoxycarbonyl)thioureido)-2-(tert-butoxycarbonyl)propanoic acid and 2-amino-4-(1-(benzyloxy)-3-(ethoxycarbonyl)thioureido)-butanoic acid have been synthesized respectively via an opening reaction of α-(N-Boc) amino-β-lactone and a reaction of substitution carried out on γ-iodohomoalanine. The structures of the synthesized compounds were established by 1 H-NMR, MS data and elemental analysis.
