L-MTP-PE (1), an immunomodulator and its metabolite MDP (4) were synthesized from labeled l-alanine and its protected derivative, respectively. The key intermediate product for the labeled L-MTP-PE synthesis, [13C3,D4]-alanyl-cephalin (2A), was synthesized from [13C3,D4]-l-alanine (3A) in three steps. The key intermediate product for labeled MDP synthesis, amine 11, was prepared from [13C3,15N]-Boc-l-alanine (5A) in two steps.
