该中间体在本合成路线中的序号：(XIV)In an alternative procedure, deoxyribose (XIV) was reduced to 2-deoxy-D-erythropentitol (XV) with NaBH4. Acid-catalyzed cyclization of (XV) produced (IX), which was converted to triflate (XVI) using trifluoromethanesulfonic anhydride and pyridine. Displacement with tetrabutylammonium azide provided azido derivative (XVII). Further treatment with trifluoromethanesulfonic anhydride gave triflate (XVIII), which was then displaced with potassium thioacetate to yield thioester (XII). This was hydrolyzed with NaOMe as above to furnish thiol (XIII).
