Abstract Two types of mixed ester of β- d -ribofuranose were synthesized. The first had the same groups attached to O-1, 2, and 3, and the second had the same groups attached to O-2, 3, and 5. The three esters obtained in the highest yields, starting from d -ribose, were then converted into the halides and nitriles. Of the esters studied, the best suited for conversion into the nitrile was 1- O -acetyl-2
