Abstract
The disposition of cholesterol inside the �cyclodextrin
cavity (�CD)
was deduced from
oxidation of cholesterol secondary alcohol groups by Ca(OCl)2 and H2O2 in the pyridine–acetic
acid system. The amount of cholest4ene3one
formed was found to be proportional to the concentration
of �cyclodextrin,
resulting in 56.1% of ketone. The oxidation rate was enhanced by
�cyclodextrin
and its methyl, polymer and 1 : 1 copper(II)–�cyclodextrin
derivatives. Detailed
investigations involving UVvisible,
13Cand
1HNMR
(T1, 1D NOE and ROESY) spectroscopic
studies were carried out. A binding constant value of 15,385 � 1500 M
