more easily approached by dioxirane than that at position C80,
which gives 9a as the major product (Fig. 15). Thus, the binding
geometries of 9 to g-CD and steric hindrance lead to high site-
selectivity in the C–H bond hydroxylation of 9 (9a : 9b ¼ 5 : 1).

Conclusions
In summary, we have investigated the hydroxylation of various
cyclohexanes with dioxirane generated in situ through supra-
molecular control using b-CD and g-CD as the hosts. The results
indicated that CDs could act as reaction vessels for hydroxylation
reactions performed in water without the use of organic solvents.
The stoichiometries of inclusion complexation between b-CD or
1
g-CD and cyclohexanes were determined by H NMR titration.

The effect of b-CD and g-CD as supramolecular hosts on chemo-
selective C–H bond hydroxylation of trans and cis isomers of
disubstituted cyclohexanes was investigated. Site-selective C–H
bond hydroxylation of (+)-menthol (9) was achieved through
inclusion complex formation with b-CD and g-CD in water.
