state. The intramolecularoxidation of ketone 6 showed the preference for a tertiary delta C-H bond over a secondary one. This intramolecularoxidation method can be extended to the oxidation of the tertiary gamma' C-H bond of ketones 9 and 10. For ketone 11 with two delta C-Hbonds and one gamma' C-H bond linked respectively by a sp(3) hydrocarbon tether and a sp(2) ester tether, the oxidation took place
