A synthetic method for 2 ′,3 ′-dideoxyinosine (ddI) from inosine was established via radical deoxygenation of N1,5 ′-O-diprotected-2 ′,3 ′-bis-S-methyl dithiocarbonate of inosine derivatives. The radical deoxygenation proceeded smoothly to give the desired dideoxy compounds in good yields using 1-ethylpiperidinium hypophosphite and triethylborane. Benzyl or p-methoxybenzyl protection of inosine at
通过肌苷衍生物的N1,5'-O-diprotected-2',3'-双-S-甲基二硫代碳酸酯的自由基脱氧,建立了由肌苷合成2',3'-二脱氧肌苷(ddI)的方法。使用 1-乙基哌啶鎓次磷酸盐和三乙基硼烷,自由基脱氧顺利进行,以良好的收率得到所需的双脱氧化合物。N1、5'-O-位肌苷的苄基或对甲氧基苄基保护对ddI合成有效。
