Participants

Reaction Steps

In a 250 mL round-bottomed flask 1.3 g (7.7 mmol, 2 eq.) of mCPBA was added to a solution of (2S,7′R)-7-chloro-4,6-dimethoxy-2′,7′-dimethyl-7′,8′-dihydro-3H,5′H-spiro[benzofuran-2,6′-quinoline]-3,5′-dione (1.5 g, 3.9 mmol, 1.0 eq) in 45 mL of dichloromethane. The mixture was left under agitation at ambient temperature for 16 h, then concentrated under reduced pressure. The residue was dissolved in AcOEt. The organic phase was washed with 10% Na2S2O3 solution, then a saturated NaHCO3 solution, then brine solution and dried over Na2SO4, filtered and concentrated under reduced pressure. A yellow solid (1.6 g) was obtained with a yield of 100%.
