Abstract:
:The synthesis of the ethylenediamine-connected cyclodextrin dimer is reported, together with the syntheses of several reference cyclodextrinylamines. Each compound displayed enhanced transacylation or transphosphorylation of activated substrates, with the primary amine-bearing monocyclodextrin compound showing the greatest activity. No special rate advantage was observed for this cyclodextrin dimer, although such effects do exist in other cycloextrin dimers reported previously.
