  • Molecular Recognition Study on Supramolecular System. 14.<sup>1</sup> Synthesis of Modified Cyclodextrins and Their Inclusion Complexation Thermodynamics with <scp>l</scp>-Tryptophan and Some Naphthalene Derivatives

    A series of beta-cyclodextrin derivatives, carrying pyridinio (4-6), phosphonyl (7, 8), seleno (9-11), m-and p-picolinyl (12, 13), o-chloroanilino (16), 8-quinolyl. (17), furfuryl (18), and 9-fluorenyl (19) moieties in the side chain, were newly synthesized, and their complexation behavior was assessed and discussed thermodynamically, using L-tryptophan and a few naphthalene derivatives as representative guests. Calorimetric titrations have been performed at 25.0 degrees C in buffered aqueous solution (pH 7.20) to give the complex stability constants and thermodynamic parameters for the 1:1 inclusion complexation of these guests with the native and modified alpha-, beta-, and/or gamma-cyclodextrins (1-20). All of the chemical modifications to the primary side of cyclodextrins examined led to significant changes in complex stability and thermodynamic parameters, which are elucidated in terms of the conformational, electrostatic, hydrogen-bonding, and hydration effects. Thermodynamically, the inclusion complexation is mainly enthalpy-driven with a negative or minor positive entropic contribution, which in some cases determines the complex stability. The induced circular dichroism spectral analyses of these cyclodextrin derivatives indicated that the aromatic moiety in modified beta-cyclodextrins (4-6, 9-19) only shallowly penetrates into the hydrophobic cavity of beta-cyclodextrin, while the phenyl phosphate and fluorenyl moieties in 7 and 20 are embedded into the hydrophobic cavity of beta-cyclodextrin because of the longer linking chain. Using all the thermodynamic data for a wide variety of cyclodextrin derivatives obtained in this and previous studies, the entropy changes (T Delta S) were plotted against the enthalpy changes (Delta H) to give an excellent linear relationship. The slope (alpha) of 1.02 and an intercept (T Delta S-o) of 4.3 of the regression line indicate substantial conformational changes and extensive desolvation caused upon complexation,respectively.

    investigate the inclusion phenomena. The results obtained demonstrate that the modified β-cyclodextrin (1) is highly sensitive to the size/shape and conformational rigidity of guest molecules, giving fairly good molecular selectivity up to 114 for adamantan-1-ol/cyclopentanol and relatively high E/Z selectivity up to 2.7 for geraniol/nerol. Interestingly, all of the modified β-cyclodextrins employed displayed
