, p. 7003 - 7007 (2016)
With tetrabutylammonium iodide (TBAI) as the catalyst and tert-butyl hydroperoxide (TBHP) as the oxidant, a simple metal-free protocol has been developed for the synthesis of α-acyloxycarbonyl compounds from carbonyl compounds and α-oxo carboxylic acids via decarboxylative coupling reaction. The target products could be obtained in moderate to high yields.

Paragraph 0020-0022, (2021/08/06)
The invention discloses a preparation method of an alpha-acyloxy ketone compound, which comprises the following steps of adding a 1, 3-dicarbonyl compound, carboxylate and a catalyst alkyl halide into an organic solvent, and stirring and reacting for 0.5-1 hour at the temperature of 20-30 DEG C to obtain a reaction product, namely a mixture, performing purification treatment on the mixture to obtain alpha-acyloxy ketone, wherein the molar ratio of the 1, 3-dicarbonyl compound to the carboxylate to the alkyl halide is 1: 1: 1. According to the method, carboxylate with low cost is selected as an acyloxylation reagent, reaction conditions are mild and green, a 1, 3-dicarbonyl compound is taken as a raw material, and a novel method for efficiently, simply and conveniently constructing a C-O bond is successfully realized through activation of a carbonyl alpha-position C-H bond and subsequent cascade reaction, so that a series of alpha-acyloxyketone compounds are obtained.
