合成路线1
该中间体在本合成路线中的序号：(X)1,2-Dideoxy-D-ribose (IX) was converted to bismesylate (X) upon treatment with methanesulfonyl chloride and pyridine. Displacement of the primary mesylate group of (X) with LiN3 in DMF gave azide (XI). The secondary mesylate group was further displaced with potassium thioacetate to provide (XII). Thiol (XIII) was then prepared by hydrolysis of the thioester function with NaOMe in THF.
