Participants

Reaction Steps

A mixture of 300 mg (1.07 mmol) of the less polar (2R,3R or S)-2-benzyl-3-hydroxy-5,5-dimethyl-4-oxo-hexanoate and 1.07 ml of 1N sodium hydroxide solution in 10 ml of methanol is stirred at room temperature for 3 hours. Thereafter, the reaction mixture is neutralized with 1.07 ml of 1N hydrochloric acid and evaporated under reduced pressure. The residue is triturated with ethyl acetate and the insoluble solid is separated. After evaporation of the ethyl acetate phase there are obtained 180 mg of (2R,3R or S)-2-benzyl-3-hydroxy-5,5-dimethyl-4-oxohexanoic acid as a colourless solid, MS: 231 (M-CH3 -H2O)+.
