TOTAL SYNTHESIS OF THERMOACTINOAMIDE A AND ITS ANALOGUE

Thermoactinoamide A, showing remarkable antibacterial properties, is a novel cyclic hexapeptide which was originally isolated from thermophilic bacterium. We disclosed here the first total synthesis of thermoactinoamide A and its analogue, anti-thermoactinoamide A, by the Fmoc solid-phase peptide synthesis and subsequent efficient macrolactamization. Thermoactinoamide A and its analogue can be obtained in 74% and 46% overall yield respectively without any isomerization under the developed methodology.
