Eudistomidin B, isolated from a marine tunicate, was originally assigned a tetrahydro-β-carboline structure with a 2-p-tolylethanamine residue. Asymmetric total synthesis of the reported structure of natural product, which features an intramolecular diastereoselective Pictet-Spengler cyclization, suggests that the reported structure of the natural product needs to be revised.
从海洋被膜中分离得到的Eudistomidin B最初被分配为带有2- p- tolylethanhanamine残基的四氢-β-咔啉结构。报告的天然产物结构的不对称全合成具有分子内非对映选择性Pictet-Spengler环化特征,这表明报告的天然产物结构需要修改。
