Three kinds of oudemansin X, (-)-1, (+)-1 and (±)-1, were totally synthesized. The key point in the present chiral synthesis was the enantioselective acetylation of the racemic alcohols, (±)-5 and (±)-8, using lipase in an organic solvent. The synthetic (-)-1 was found to exhibit strong antifungal activity against several molds and yeasts.
全合成了(-)-1、(+)-1和(±)-1三种oudemansin X。目前手性合成的关键点是在有机溶剂中使用脂肪酶对外消旋醇(±)-5 和(±)-8 进行对映选择性乙酰化。研究发现,合成的 (-)-1 对多种霉菌和酵母菌具有很强的抗真菌活性。
