Six crown ethers containing two coumarin (11, 13,14,16,17 and 19) or two 1-aminonaphthalene (15 and 20) fragments as sidearms and two crown ethers bearing one coumarin (12 and 18) arm were synthesized by a nucleophilic substitution of the secondary macrocyclic amine function on the alkyl halide. The major products of these reactions were the diazadithiacrown ethers containing two sidearms. In some
通过亲核反应合成了含有两个香豆素(11,13,14,16,17和19)或两个1-氨基萘(15和20)片段作为侧臂的六个冠醚和带有一个香豆素(12和18)臂的两个冠醚。烷基卤上仲大环胺官能团的取代。这些反应的主要产物是含有两个侧臂的重氮二氮杂冠醚。在某些情况下,单臂重氮杂二氮杂冠酮醚是次要产物,尽管1.0毫摩尔的大环二胺使用了2.5摩尔以上的卤代烷。
