Trichormamide C Structural Confirmation through Total Synthesis and Extension to Analogs
Résumé
The growing interest in marine natural substances as potential new drugs has made total synthesis a real asset for structure confirmation. Trichormamide C (1), a cyclic lipopeptide isolated from the cyanobacteria Oscillatoria sp., is characterized by the presence of nonproteinogenic amino acids in the sequence. Trichormamide C structural confirmation was carried out through the implementation of a flexible synthesis resulting in two new analogs (3 and 4).
