[GRAPHICS]The synthesis of two tamandarin B analogues in which the N,O-Me(2)Tyr(5) unit was replaced by N-Me-phenylaianine (N-MePhe(5)) and (S)-2(methylamino)-3-(naphthalen-2-yl)propanoic acid (N-MeNaphth(5)) is described. The choice of the macrocyclization site was crucial to achieve satisfactory macrolactamization. Coupling between norstatine (Nst(1)) and threonine (Thr(6)) afforded only a 15% yield, while lactamization between proline (Pro(4)) and the aromatic moiety could be achieved in 65% yield.
