Synthesis of (+)-testudinariol A, a triterpene metabolite of the marine mollusc Pleurobrancus testudinarius

Testudinariol A (1) is an ichthyotoxic and structurally unusual triterpene alcohol isolated from the skin and the mucus of the marine mollusc Pleurobrancus testudinarius. A stereoselective synthesis of (+)-1 was achieved by starting from (R)-glycidol.
