We designed novel Ca(2+)-mobilizing purine nucleotides, cyclic ADP-carbocyclicribose 4, and its inosine congener 5, and C-glycosidic adenophostin A 6. In the synthesis of cADPR analogs, the intramolecular condensation to form the pyrophosphate linkage should be the key step. We developed an efficient method for forming such an intramolecular pyrophosphate linkage by the activation of the phenylthiophosphate
我们设计了新颖的Ca(2+)动员嘌呤核苷酸,环ADP-碳环核糖4,其肌苷同源物5和C-糖苷腺苷A6。在合成cADPR类似物时,分子内缩合形成焦磷酸酯键应为关键步骤。我们开发了一种通过用I2或AgNO3活化苯硫代磷酸酯基团来形成分子内焦磷酸酯键的有效方法。使用该方法,我们合成了目标化合物4和5。使用暂时的硅链自由基偶联反应来构建(3'alpha,1“ alpha)-C,可以合成腺磷素A的C-糖苷类似物6。 -糖苷结构为关键步骤。
