V. Caplar et al., A NOVEL TYPE OF RIGID MACROCYCLE WITH BIS(3-URACILYL)METHANE AND HEXADIYNE UNITS - THE URACILOPHANE, Croatica chemica acta, 69(4), 1996, pp. 1617-1631
Synthesis of the first uracilophane 15, constructed from two bis(3-ura
cilyl)methane units and two hexadiyne bridges connecting uracil N(1)-a
toms, is described. The conformational properties of 15 investigated b
y molecular dynamics revealed low energy conformations with partly or
fully stacked phenyl-uracil or phenyl-phenyl pairs.
