Abstract

The total synthesis of the proposed structure of similanamide, a cyclic hexapeptide recently isolated from the marine sponge-associated fungus Aspergillus similanensis KUFA 0013, was achieved by solid-phase synthesis of a linear precursor and solution-phase macrolactamization. The NMR spectra of our synthetic final product were not identical to those of the isolated material and led us to conclude that similanamide is identical to PF1171C, a previously reported diastereomeric hexapeptide.
