Total Synthesis and Revision of Absolute Stereochemistry of Antillatoxin, an Ichthyotoxic Cyclic Lipopeptide from Marine Cyanobacterium Lyngbya majuscula
Antillatoxin is an ichthyotoxic cyclic lipopeptide isolated by Gerwick and co-workers from the marine cyanobacterium Lyngbyamajuscula collected in Curaçao. Although we have finished the stereoselective total synthesis of antillatoxin having the proposed structure with (4S,5R)-configuration, we have found that the synthetic sample was not identical with the natural one and the proposed structure should
