実験手順

9.6 of 2-(3,4-dimethoxyphenyl)-m-dithiane-1,1,3,3-tetraoxide (prepared as described in Example 2) are dissolved in 35 ml of dimethylformamide and, with stirring under argon, treated with 1.2 g of sodium hydride at room temperature. The suspension is stirred at 40° C for a further 0.5 hour, then cooled and treated with 2.8 g of epichlorohydrin. The mixture is then heated at 100° C for 16 hours. After cooling to room temperature, the suspension is poured on to water and the oily material extracted with chloroform. After evaporation of the solvent, the residue is chromatographed on silica gel with chloroform/ethanol (98:2). The 2-(3,4-dimethoxyphenyl)-2-(2,3-epoxypropyl)-m-dithiane-1,1,3,3-tetraoxide obtained is recrystallized from methylene chloride/ethanol and has a melting point of 175°-176° C.
