実験手順
42 g of 1-bromo-6,7-epoxyheptane were introduced into a mixture of 400 ml of tetrahydrofuran and 235 ml of water, which had been adjusted to pH 2 with perchloric acid, at room temperature. After stirring at room temperature for 8 hours, the mixture was neutralized, evaporated under reduced pressure and the residue was extracted with methylene chloride. After removal of the solvent, 41.5 g of crude 1-bromo-6,7-dihydroxyheptane were obtained.
