Yield:226709-43-9 90%

Reaction Conditions:

with sodium hydride in 1,4-dioxane;mineral oil at 50;Cooling with ice;

Steps:

3.3. General procedure for the synthesis of dianhydrosugars (12 and 13)

To a solution of the iodoalcohol (10/11, 1 g) in anhydrous dioxane (10 mL) maintained over an ice-bath was added NaH (60% suspension in mineral oil, 1.1 mol equiv) and stirred. After 15 min, continuation of the reaction for a further period of 12 h was carried out at 50 °C. After the completion of the reaction it was filtered through a Celite-bed and the filtrate was concentrated under reduced pressure. The crude product was purified by column chromatography.
