Synthesis of the Scalarane Sesterterpenoid 16-deacetoxy-12-epi-scalarafuranacetate

[摘要]：The marine natural product 16-deacetoxy-12-epi-scalarafuranacetate, isolated from Spongua officinalis, was synthesized in 18 linear steps, starting from (-)-sclareol, with high stereoselectivity and an overall yield of 6.1%. The intermediate 16-deacetoxy-12-epi-scalarafuran could be easily transformed into a series of natural scalarane sesterterpenoids in a few steps.
