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. The residue was washed with EtOAc, and the filtrate was evaporated to give a residue that was purified by chromatography [silica gel, EtOAc–hexane (1:20)] to give a yellow solid; yield: 610 mg (75%); mp 156–157 °C. cis-4 ¹H NMR (400 MHz, CDCl₃): δ = 6.93 (s, 1 H), 6.69 (s, 1 H), 6.56 (dd, J = 10.6, 1.8 Hz, 1 H), 5.84 (dd, J = 10.6, 6.7 Hz, 1 H), 3.84 (s, 3 H), 3.46–3.38 (m, 1 H), 3.32–3.23 (m, 1 H), 2.96 (dd, J = 14.0, 10.9 Hz, 1 H), 2.56 (dd, J = 14.0, 6.4 Hz, 1 H), 2.52–2.42 (m, 1 H), 2.41–2.27 (m, 2 H), 2.01–1.89 (m, 1 H), 1.68–1.59 (m, 1 H), 1.26–1.17 (m, 9 H), 0.99 (s, 3 H). ¹³C NMR (101 MHz, CDCl₃): δ = 211.5, 155.8, 138.5, 134.5, 130.9, 128.9, 128.4, 128.2, 111.7, 56.2, 55.6, 52.8, 41.3, 38.6, 34.5, 32.6, 29.8, 26.6, 22.8, 20.1. trans-4 ¹H NMR (400 MHz, CDCl₃): δ = 6.96 (s, 1 H), 6.73 (s, 1 H), 6.50 (dd, J = 12.2, 2.3 Hz, 1 H), 5.78 (dd, J = 12.2, 3.9 Hz, 1 H), 3.82 (s, 3 H), 3.31–3.21 (m, 2 H), 2.84–2.68 (m, 2 H), 2.55–2.42 (m, 1 H), 2.40–2.28 (m, 2 H), 1.80–1.60 (m, 2 H), 1.19 (dd, J = 6.9, 1.2 Hz, 6 H), 1.09 (s, 3 H), 1.08 (s, 3 H). ¹³C NMR (101 MHz, CDCl₃): δ = 211.5, 155.8, 138.4, 134.5, 130.9, 128.9, 128.4, 128.1, 111.7, 56.1, 55.6, 52.8, 41.3, 38.6, 34.5, 32.6, 29.8, 26.5, 22.8, 20.0.
