convenient method to prepare α-alkoxy ketones has been developed by oxidative coupling of aryl methyl ketones and alcohols. With aqueous tert-butyl hydroperoxide (6.0 equiv.) as the oxidant, tetrabutylammonium iodide (20 mol-%) as the catalyst, and TsNHNH2 (1.0 equiv.) as the additive, ketones underwent direct alkoxylation to give α-methoxy or α-ethoxy ketones in moderate to good yields.

a solid support could be simply and efficiently prepared by reaction of the corresponding resin-bound acid chlorides with excess TMSdiazomethane, without any bases. These α-TMSdiazoketones were used via carbenes or carbenoids for a variety of solid-phase reactions. These useful solid-phase reactions allow efficient construction of diverse compound libraries by use of combinatorial chemistry, due to
