β-D-ribofuranose 13, This compound, or the related glycosyl chloride, was condensed with several purine and pyrimidine bases and all protecting groups were removed by mild alkaline treatment via a series of intramolecular cyclizations and hydrolysis. In this manner the phosphonate analogs of nucleoside 3'-phosphates derived from adenine, 6-dimethylaminopurine, uracil, thymine, and cytosine were prepared
描述了3'-脱氧-3'-二羟基次膦酰基甲基核糖核苷3(核苷3'-磷酸的等排磷酸酯类似物)的一般合成路线。这涉及用亚甲基二膦酸四乙酯6烷基化1,2; 5,6-二-O-异亚丙基-α-D-核糖-六呋喃糖-3-ulose 7),然后进行立体选择性催化还原并裂解C 6生成3-脱氧-3-二乙氧基次膦基甲基-1,2-O-异亚丙基-α- D12a。苯甲酰化,然后进行乙酰分解,然后生成关键的结晶中间体1,2-二-O-乙酰基-5-O-苯甲酰基-3-脱氧-3-二乙氧基次膦基甲基-β-D-呋喃呋喃糖13将该化合物或相关的糖基氯与几个嘌呤和嘧啶碱基缩合,并通过一系列分子内环化和水解,通过温和的碱处理除去所有保护基。以这种方式制备了衍生自腺嘌呤,6-二甲基氨基嘌呤,尿嘧啶,胸腺嘧啶和胞嘧啶的核苷3'-磷酸的膦酸酯类似物。
