The synthesis of a potential precursor of a multi-interlocking ring system is described. This precursor consists of two lipophilic 4,7-di-(n-hexyl)-2,9-di-phenyl-1,10-phenanthroline moieties linked by a diacetylenic bridge and ended by two alkyne groups. The Cu(I)-templated double threading of this bis-chelate string into two coordinating macrocycles was demonstrated. An intramolecular cyclization
描述了多联环系统的潜在前体的合成。该前体由两个亲脂性的4,7-二-(正己基)-2,9-二苯基-1,10-菲咯啉部分通过二炔桥连接并由两个炔基封端。这双螯合物字符串的Cu(I)模板双线程到两个协调大环被证明。这个预先组织好的系统的分子内环化(格拉斯氧化)导致相应的dicopper(I)[3] -catenate的收率为48%。
