A flexible synthesis of the four stereoisomeric enantiomerically pure 5′-nor carbocyclic adenosine analogues 4b, ent-4b, 5b and ent-5b starting from the common enantio-merically pure allylic monoacetate 3 has been developed. Each of the nucleoside analogues was transformed into the corresponding 4′-phosphonates and subsequently into the diphosphoryl-phosphonates 4e, ent-4e, 5e, and ent-5e, respectively
已经开发了从常见的对映体纯的烯丙基单乙酸酯3开始的四个立体异构对映体纯的5'-去碳环腺苷类似物4b,ent - 4b,5b和ent - 5b的灵活合成。将每个核苷类似物分别转化为相应的4'-膦酸酯,然后分别转化为二磷酸基膦酸酯4e,ent - 4e,5e和ent - 5e。
