Procedure

A suspension of peracetyl-D-arabinose (prepared according to the method of Evelyn, Carbohydrate Res., 1982, 100:55-61) (3 g, 9.4 mmol) and alumina (50 mg) in methanol (200 ml) was refluxed for 5 hrs. After filtration of the inorganic substance, the filtrate was concentrated in vacuo to give 2,3,4-tri-O-acetyl-D-arabinopyranose (1.46 g, 56%) as an oil.
