実験手順

5.2 g of (2RS,3SR)-5-oxotetrahydrofuran-2,3-dicarboxylic acid in 88 ml of acetone was stirred with 6.5 g of 1,1'-dicyclohexylcarboriimide at room temperature for 2 hours. After addition of 3.26 ml of benzyl alcohol, the reaction solution was stirred at the same temperature for 12 hours. The insolubles were filtered off, and the filtrated was concentrated under reduced pressure. The residue was purified by silica gel column chromatography [hexane/ethyl acetate=4/1→chloroform/methanol=50/1] to give 7.93 g of the title compound as a yellow solid.
