rearranged eunicellane skeleton can be obtained in one step by treatment of an α,β-unsaturated diterpenoid with samariumdiiodide generated in situ in THF. NOESY-based structure analysis revealed the presence of an ansa bridge across a twist-boat six-membered ring. diterpenoids - retro-aldol reaction - samariumdiiodide - isoeunicellane - NOESY-based analysis
