Synthesis of the Icetexane Diterpenoids (±)-Rosmaridiphenol, (±)-Pisiferin, and (±)-Barbatusol from Abietane

Abstract

We report the rearrangement of abietane core with trifluoromethanesulfonic anhydride in pyridine to afford the icetexane core, a key intermediate for total syntheses of the structurally intriguing and biologically active compounds (±)-barbatusol, (±)-rosmaridiphenol, and (±)-pisiferin.

Key words

icetexane - abietane - diterpenoids - pisiferin - rosmaridiphenol - barbatusol - ring expansion

The mixture was then diluted with H₂O (50 mL) and extracted with EtOAc (2 × 30 mL). The filtrate was washed sequentially with 10% aq NaHCO₃ (2 × 10 mL), 1 M HCl (10 mL), and brine (5 mL), then dried (Na₂SO₄) and filtered.
