  Concise Syntheses of the Natural Products (+)-Sylvaticin and (+)-cis-Sylvaticin

  摘要：

  Two concise syntheses of the natural products cis-sylvaticin and sylvaticin are reported, using oxidative cyclization methodology as the key step. A sequential solvolysis/hydride shift/intramolecular reduction cascade was used to establish the trans stereochemistry of one of the THF rings of sylvaticin.
