  Synthesis and calcium antagonistic activity of a series of diethyl benzofuryl, benzothienyl and benzogammapyronyl benzylphosphonates

  摘要：

  In this work we present about 15 original heterocyclic diethyl benzylphosphonate analogues of fostedil, in which we have varied the nature of the heterocycle, the substituents or the phosphonic group, or even the position of this latter. Three diethyl 4-(2-benzofuryl) benzyl phosphonates exhibited slightly higher calcium antagonism than the control. Solely substitution with a fluorine atom was able to maintain activity, whereas the other modifications always decreased it.

  phenols, boronic acids or other organoboron reagents, and trichloroethylene. The overall process requires only two synthetic steps, with the key step being a one-pot sequential Suzuki cross-coupling/direct arylation reaction. The method tolerates many useful functional groups and does not require the installation of any other activating functionality. The modular nature of the process permits the rapid

  2-取代的苯并[b]呋喃可以很容易地由简单的苯酚、硼酸或其他有机硼试剂和三氯乙烯组装而成。整个过程只需要两个合成步骤，关键步骤是一锅顺序 Suzuki 交叉偶联/直接芳基化反应。该方法可以容忍许多有用的功能组，并且不需要安装任何其他激活功能。该过程的模块化特性允许使用基本相同的化学物质快速合成许多类似物，在药物开发中具有特殊价值。动力学同位素效应研究的结果和对该过程区域选择性的研究表明，直接芳基化步骤很可能不涉及亲电钯化。

  synthesis of benzo[b]furans from 1-aryl- or 1-alkylketones using nonprecious transition metal catalysts have been developed. Regioselective iron(III)-catalyzed halogenation of the aryl ring, followed by iron- or copper-catalyzed O-arylation allowed the synthesis of various structural analogues, including the benzo[b]furan-derived natural products corsifuran C, moracin F, and caleprunin B.
