  液相直接氟化法合成全氟羧酸膜单体

  摘要：

  已经开发了一种从非氟化化合物制备全氟化羧酸膜单体的新合成方法。合成路线中的关键步骤是与元素氟进行液相直接氟化反应。由烃二醇和全氟化酰基氟制备的部分氟化二酯直接氟化，然后进行热消除，得到全氟化二酰基氟，其为全氟化羧酸膜单体的前体。

  Practical catalytic cross-coupling of secondary alkyl electrophiles with secondary alkyl nucleophiles under Cu catalysis has been realized. The use of TMEDA and LiOMe is critical for the success of the reaction. This cross-coupling reaction occurs via an S(N)2 mechanism with inversion of configuration and therefore provides a general approach for the stereocontrolled formation of C-C bonds between

  已经实现了在铜催化下仲烷基亲电试剂与仲烷基亲核试剂的实际催化交叉偶联。TMEDA 和 LiOMe 的使用对于反应的成功至关重要。这种交叉偶联反应通过构型反转的 S(N)2 机制发生，因此为手性仲醇的两个叔碳之间立体控制形成 CC 键提供了通用方法。
• Bifunctional Acyclic Nucleoside Phosphonates. 1. Symmetrical 1,3-Bis[(phosphonomethoxy)propan-2-yl] Derivatives of Purines and Pyrimidines

  We report here a general method for the synthesis of new symmetrical bis-phosphonates of acyclic nucleosides. 1,3-Bis[(diisopropoxyphosphoryl)methoxy] derivatives of purine and pyrimidine bases were prepared by their reaction with 1,3-bis[(diisopropoxyphosphoryl)-methoxy]propan-2-yl tosylate. Cytosine, uracil and thymine provided regiospecificallyN¹-isomers. This alkylation regiospecificity applies to several other tosylates of primary and secondary alcohols as well. 6-Chloropurine and 2-amino-6-chloropurine were alkylated in N⁹position. Resulting bis-phosphonates were converted to the respective free phosphonic acids and tested for antiviral and cytostatic activity. Despite the fact that no biological activity was found so far, the outcome of this work can serve as a useful tool in synthesis of novel groups of acyclic nucleoside phosphonates (ANPs).

  我们在这里报告了一种合成新的无环核苷酸对称双膦酸的一般方法。嘧啶和嘧啶碱的1,3-双[(二异丙氧磷酰基)甲氧基]衍生物通过它们与1,3-双[(二异丙氧磷酰基)甲氧基]丙烷-2-基对甲苯磺酸酯的反应制备。胞嘧啶、尿嘧啶和胸腺嘧啶提供了具有特定区域选择性的N1异构体。这种烷基化的区域选择性也适用于其他几种主要和次要醇的对甲苯磺酸酯。6-氯嘌呤和2-氨基-6-氯嘌呤在N9位烷基化。所得的双膦酸酯被转化为相应的自由膦酸，并进行了抗病毒和细胞毒活性测试。尽管目前尚未发现任何生物活性，但这项工作的结果可以作为合成新型无环核苷酸膦酸酯（ANP）的有用工具。
