Reaktionsschritte

To a solution of (S)-1-phenyl-1,3-propanediol (8.0 g, 52.6 mmol) in dichloromethane (80 ml) were added at 0° C. acetic anhydride (5.5 ml) and pyridine (4.7 ml). The mixture was stirred for 6 hours at the same temperature range and for 1.5 hour at room temperature. The reaction mixture was washed with an aqueous solution of sodium hydrogencarbonate, water and a saturated aqueous saline solution, successively. The solvent was distilled off under reduced pressure. The residue was subjected to a silica gel column chromatography to give 4.8 g of (S)-3-hydroxy-3-phenylpropyl acetate. Physico-chemical properties and spectral data of these products are shown in [Table 7].
