A novel type of rigid macrocycle with bis(3-uracilyl)methane and hexadiyne units - the uracilophane

Synthesis of the first uracilophane 15, constructed from two bis(3-uracilyl)methane units and two hexadiyne bridges connecting uracil N(1)-atoms, is described. The conformational properties of 15 investigated by molecular dynamics revealed low energy conformations with partly or fully stacked phenyl-uracil or phenyl-phenyl pairs. [References: 31]
