  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.

  The first example of sole direct C–H bond arylation of benzo[b]furans with aryl chlorides was achieved catalyzed by a well-defined NHC-Pd(II)-Im complex. Under the suitable conditions, all reactions involving kinds of benzo[b]furans and (hetero)aryl chlorides proceeded well to give the desired C2-arylated benzo[b]furans in sole regioselectivity in acceptable to high yields, providing an efficient and

  明确定义的NHC-Pd（II）-Im络合物催化了苯并[ b ]呋喃与芳基氯的唯一直接C-H键芳基化反应。在合适的条件下，所有涉及各种苯并[ b ]呋喃和（杂）芳基氯化物的反应均能顺利进行，从而以唯一的区域选择性提供所需的C2-芳基化苯并[ b ]呋喃，并以高收率接受，从而提供了有效而经济的途径用于苯并[ b ]呋喃的直接C2-H键芳基化。
