Antillatoxin is an ichthyotoxic cyclic lipopeptide isolated by Gerwick and co-workers from the marine cyanobacterium Lyngbya majuscula 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
抗毒素是由盖威克及其同事从库拉索岛收集的海洋蓝藻金刚鹦鹉中分离出来的一种鱼腥毒素环脂肽。尽管我们已经完成了具有拟议结构的(4 S,5 R)-构型的抗llatoxin的立体选择性全合成,但我们发现合成样品与天然样品不完全相同,应修改拟议的结构。进一步,我们的合成努力最终达到了天然形式的抗llatoxin的第一个全合成,证明了天然的具有(4 R,5 R)-构型。
