A total synthesis of the cyclic lipodepsipeptide natural product orfamide A was achieved. By developing a synthesis format using an aminoacid ester building block and SPPS protocol adaptation, a focused library of target compounds was obtained, in high yield and purity. Spectral and LC‐HRMS data of all library members with the isolated natural product identified the 5Leu residue to be d‐ and the 3’‐OH group to be R‐configured. The structural correction of orfamide A by chemical synthesis and analysis was confirmed by biological activity comparison in Chlamydomonas reinhardtii, which indicated compound configuration to be important for bioactivity. Acute toxicity was also found against Trypanosoma brucei, the parasite causing African sleeping sickness.
