Popis | Axially substituted [n]staffanes I form inclusion complexes with â-cyclodextrin (II) in water. 1H NMR spectrum of a water solution of beta-cyclodextrin II has shown apparent changes of chemical shifts of intracavity protons H-3 and H-5 upon addition of [2]staffane-3,3-diol (Ia)into the solution. Nuclear Overhauser effect has been observed between beta-cyclodextrin protons H-3, H-5 and bridge protons of the diol Ia. The method of continuous variations applied to the both complexation sensitive chemical shifts revealed formation of host-guest complex of 1:1 stoichiometry. |
