| Description |
Vanillin was found to form a stable complex with 0-cyclodextrin. A binding constant value of 1.11 X
lo4 M-' was determined for the 1:l complex. 'H NMR chemical shift differences and circular dichroism
spectra indicated that both phenolic end and aldehyde end were affected by complexation. 2D
nuclear Overhauser enhancement spectroscopy indicated proximity of OCH, in vanillin to the anomeric
protons of P-cyclodextrin. 1D difference NOE experiments have revealed that vanillin exists
with the phenolic end nearer to the narrower end and the aldehyde end to the wider end of the torusshaped
0-cyclodextrin molecule.
