Abstract

A practical and scalable enantioselective total syntheses of the marine anticancer sesquiterpene quinone meroterpenoids (+)-dysidavarones A–C has been accomplished. The central bridged bicyclo[3.3.1]nonane structure of dysidavarones was efficiently established by a one-pot intermolecular diastereoselective alkylation and intramolecular α-arylation of a Wieland–Miescher ketone derivative with a substituted benzylic bromide, without protection of the more-reactive C(4) carbonyl group. (+)-Dysidavarones A and ‘E’ were prepared on a 150-mg scale, demonstrating the efficiency and reliability of our synthetic route and providing sufficient amounts of the dysidavarones for further bioactivity evaluation.

Key words

total synthesis - natural products - dysidavarones - sesquiterpene quinones - meroterpenoids

  • 18 Diketone 7 A 1.0 M solution of t-BuOK in THF (0.642 mL, 0.642 mmol, 1.0 equiv) was added to a stirred solution of Wieland–Miescher ketone derivative 8 (148 mg, 0.770 mmol, 1.2 equiv) in DMF (6 mL) at 0 °C, and the resulting mixture was heated to 23 °C and stirred at this temperature for 1 h. A solution of benzylic bromide 10 (217 mg, 0.642 mmol, 1.0 equiv) in DMF (2 mL) was added over 30 min at 23 °C under argon, and the resulting solution was stirred at 23 °C for 1 h. A 1.0 M solution of t-BuOK in THF (1.93 mL, 1.93 mmol, 3.0 equiv) was added to the resulting solution at 0 °C in three portions over 30 min each, on average, and the resulting solution was stirred at 100 °C for 2 h. The reaction was quenched with sat. aq NH4Cl (10 mL) and the mixture was extracted with EtOAc (3 × 20 mL). The combined organic layers were washed with brine (5 mL), dried (Na2SO4), filtered, and concentrated under reduced pressure. The crude product was purified by flash column chromatography [silica gel, PE–EtOAc (30:1→10:1)] to give a white foam; yield: 142 mg (60%, 0.385 mmol); Rf = 0.55 (silica gel, PE–EtOAc, 3:1); [α]D 23 +36.0 (c = 1.0, CHCl3).
