corresponding α-acetoxy ketones throughgold-catalyzedintermolecular oxidation in the presence of 8-methylquinoline 1-oxide as the oxidant. The reaction probably proceeds through an α-oxo gold carbene intermolecular O–H insertion. A variety of terminal alkynes were efficiently converted into the corresponding α-acetoxy ketones throughgold-catalyzedintermolecular oxidation in the presence of 8-methylquinoline
