Procedure
To the mixture of 1.62 g of 2-[2-(3-chlorophenyl) propen 3-yl]-2-ethylindan-1,3-dione, 0.34 g of sodium acetate trihydrate and 10 ml of chloroform was added-2.85 g of 40% peracetic acid. After refluxing for 3 hours, excess peroxide was decomposed with 10% sodium thiosulfate aqueous solution, and the organic layer was washed with water, neutralized with a saturated sodium bicarbonate aqueous solution, washed with water and with a saturated saline solution, and dried over anhydrous magnesium sulfate. After the solvent was evaporated, the residue was separated and purified by silica gel column chromatography (developing solvent: n-hexane/ethyl acetate=4/1) to obtain 1.27 g of the compound No. 53 shown in Table 2.
