The synthesis of 2′,3′-dideoxy-3′-hydroxymethylcytidine 1 was accomplished using two different approaches. First, uridine and cytidine were used to prepare the key intermediate epoxides 15 and 31 which were opened with cyanide, deoxygenated by elimination to vinyl nitriles 17 and 36, and reduced by 1,4 hydride addition to the saturated nitriles 18 and 37. Secondly, a novel Rh-catalyzed hydroformylation
2',3'-二脱氧-3'-羟甲基胞苷1的合成使用两种不同的方法完成。首先,尿苷和胞苷用于制备关键的中间环氧化物15和31,其用氰化物打开,通过消除成乙烯基腈17和36而脱氧,并通过向饱和腈18和37中加1,4氢化物还原。其次,使用新颖的Rh催化的2′,3′-二氢二氢-2′,3′-二脱氧胞苷46的加氢甲酰化反应以四个步骤制备1。还讨论了尝试使用2'-脱氧尿苷和2'-脱氧胞苷制备1。
