Synthesis of a symmetrical octamethyl-substituted cucurbituril with a dimethyl-substituted glycoluril dimer
2014
Abstract A symmetrical octamethyl-substituted cucurbituril has been synthesized in a controlled manner by using a dimer of dimethyl-substituted glycoluril, which was in turn synthesized under formaldehyde-deficient conditions. The dimer of dimethyl-substituted glycoluril and the symmetrical octamethyl-substituted cucurbituril have been characterized by NMR spectrometry, ESI mass spectrometry and single-crystal X-ray diffraction analysis. The structure of the dimer of dimethyl-substituted glycoluril is notable because it constitutes a useful new building block that could permit the formation of such cucurbit[ n ]urils with substituents in certain positions or with limited numbers of methine groups on their backbones.
