the readily available labeled starting material, sodium [14C]formate, has been developed with a good overall yield. This new method was proven to be general in the preparation of other related [4.3.0]heterocycles containing N, O, and S atoms. A concise synthesis of a model compound, 8-aza-7-deaza-5′-[14C]noraristeromycin, was achieved utilizing this methodology as a key step.
为了支持旨在发现嘌呤相关抗癌药物候选物的研究计划,已开发了一种以易于获得的标记起始原料[ 14 C]甲酸钠为原料进行吡唑并嘧啶14 C标记的方法,该方法具有较高的总收率。事实证明,这种新方法在制备其他包含N,O和S原子的相关[4.3.0]杂环中是通用的。利用此方法作为关键步骤,可以完成模型化合物8-aza-7-deaza-5'-[ 14 C] noraristeromycin的简明合成。
