Straightforward and highly efficient synthesis of α-acetoxy ketones through gold-catalyzed intermolecular oxidation of terminal alkynes
A variety of terminal alkynes were efficiently converted into the corresponding α-acetoxy ketones through gold-catalyzed intermolecular 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.
Gold-catalyzed intermolecular oxidation of terminal alkynes: Simple and efficient synthesis of α-mesyloxy ketones
A variety of terminal alkynes were efficiently converted into the corresponding α-mesyloxy ketones through gold-catalyzed intermolecular oxidation in the presence of 3,5-dichloropyridine N-oxide as the oxidant. The reaction is proposed to proceed via α-oxo gold carbene intermolecular O-H insertion. Georg Thieme Verlag Stuttgart · New York.
Iodine-mediated α-sulfonyloxylation of alkyl aryl ketones with oxone and sulfonic acids
Alkyl aryl ketones are converted into the corresponding α-sulfonyloxyketones, in moderate to excellent yields, via a novel procedure that utilizes Oxone, p-toluenesulfonic acid or methanesulfonic acid and molecular iodine in a mixture of aceton
