Ring functionalization: The total synthesis of a natural derivative of (−)-13-oxyingenol, a potent anti-HIV diterpenoid, is reported. The key steps in this synthesis include a ring-closing olefin metathesis and a Mislow–Evans-type [2,3]-sigmatropic rearrangement. This synthesis provides access to (−)-13-oxyingenol and its natural derivative in 21 steps from a synthetic intermediate previously prepared by Kigoshi and co-workers.
