To a solution of (2R,4R,5S)-4-hydroxymethyl-5-[(Z)-6-methoxycarbonyl-2-hexenyl]-2-methyl-1,3-dioxane (108 mg) in pyridine (0.5 ml) was added phenyl isocyanate (0.1 ml) and the mixture was stirred at room temperature for 30 minutes. Water (1 ml) was added and extracted with ether and the organic layers were combined and dried over anhydrous sodium sulfate. The solvent was evaporated in vacuo and the crude product was purified with preparative TLC (hexane:ether=1:1) to give (2R,4R,5S)-5-[(Z)-6-methoxycarbonyl-2-hexenyl]-2-methyl-4-phenylcarbamoyloxymethyl-1,3-dioxane (140 mg).
