NMR spectroscopy of inclusion complex of D-(-)-chloramphenicol with beta-cyclodextrin in aqueous solution.
(1)HNMR spectroscopic study in D(2)O of mixtures of D-(-)-chloramphenicol (guest), present in two tautomeric forms in solution, and beta-cyclodextrin (host) revealed the formation of 1:1 inclusion complex in which aromatic ring of the guest is tightly held by the host cavity. There seems no discrimination between the aromatic rings of two tautomers by the host.
