Reaction Steps

2,2-Dimethoxypropane and pyridinium p-toluenesulfonate (PPTS) are added to a solution of (S)-4-iodopent-4-ene-1,2-diol in dichloromethane and the mixture stirred at room temperature for 2 hours. Solvents are removed under reduced pressure and the crude product purified by flash chromatography using ethyl acetate/hexane (1:10) eluant.
