Reaction Steps

A solution of 1.15 g. (5.0 mmoles) of (S)4benzoyloxy-1-octyne (Example 899) and 1.40 g. (25 mmoles) of potassium hydroxide in 50 ml. of 10:1 methanol-water is allowed to stand at room temperature for 24 hours. The bulk of the methanol is evaporated at room temperature, and the mixture is extracted with ether. The extract is washed with brine, dried over magnesium sulfate, and evaporated to give a colorless oil, identical to 4-hydroxy-1-octyne [α]D25 = +17 ± 1.0°(C=0.77, ethyl acetate). This compound has the (S)-configuration.
