  Total synthesis of (-)-ovatolide

  摘要：

  The total synthesis of (-)-ovatolide (1), a tetracyclic indole-containing beta-glucosyl derivative with an unusual pyrano[2,3-b][1,4]dioxocan-6-one system, is described. The beta-glucosidic linkage arose from regio- and stereocontrolled reaction of a protected 1,2-epoxyglucal derivative with 4-hydroxy-5-(benzyloxy)indole, and a lactonization reaction afforded the central dioxocanone system. An alternative strategy that afforded the tetracyclic framework as a mixture of epimers is also described.
