実験手順
A mixture of 30 g of 5-hydroxy-2(5H)-furanone, 150 ml of chloroform, 50 mg of hydroquinone and 35 ml of freshly distilled cyclopentadiene was stirred at 20° C. under an inert atmosphere and stirred for 17 hours at 20°-45° C. The mixture was evaporated to dryness under reduced pressure and the residue was crystallized from an isopropyl ether-petroleum ether mixture to obtain 46.6 g of 3-hydroxy-tetrahydro-4,7-methano-isobenzofuran-1-one melting at ≃103° C.
