    • Initial attempts to couple 7 to the heptaamino-β-CD 4 core utilizing dicyclohexylcarbodiimide (DCC) and hydroxybenzotriazole or DCC and 1-hydroxy-7-azabenzotriazole as activating agents were unsuccessful, largely on account of difficulties encountered in removing the reaction byproducts. Although benzotriazol-1-yloxytripyrrolidinophosphonium hexafluorophosphate (Py-BOP) was found to be act as a suitable activator, the removal of the tripyrrolidinophosphonium oxide byproduct was far from straightforward.

    • 13C NMR resonances associated with the protons and carbons in the CD torus of these CD-based carbohydrate clusters is not entirely clear. However, we propose that the most likely explanation for this signal broadening is the expression of a dynamic phenomenon, that is, the glucose appendages cause the CD glucose residues to move on a timescale approaching that of the NMR timescale, thus causing the CD signals to broaden.
