The first total synthesis of bathymodiolamides A and B, ceramide-like metabolites of the deep-sea hydrothermal vent mussel Bathymodiolus thermophilus, was accomplished in eight linear steps starting from Garner’s aldehyde and three carboxylic acids. A sequence of vinylation of Garner’s aldehyde, N-acylation with lauric acid, dihydroxylation of the terminal alkene, and stepwise Steglich–Hassner esterifications
深海热液喷口贻贝嗜热嗜热菌的神经酰胺样代谢产物,嘧啶二醇酰胺A和B的第一个全合成过程是从Garner醛和三种羧酸开始的八个线性步骤中完成的。加纳醛的乙烯基化,月桂酸的N-酰化,末端烯烃的二羟基化以及所得邻位二醇与相应的饱和和不饱和羧酸的逐步Steglich-Hassner酯化(必须分别制备)的顺序提供了目标产品的产率分别为38%和39%。我们发现其NMR数据和抗增殖活性与报道的天然分离物之间存在明显差异。
