, p. 1097 - 1100 (2007/10/03)
The scope and limitations of intramolecular benzoin-forming reactions of aldehydes and ketones catalyzed by the combination of a thiazolium salt and a base are described. After optimization of the reaction conditions, five- and six-membered cyclic acyloins were obtained in good to excellent yields and competing reactions such as intramolecular aldol reactions were suppressed. The analogous closure of seven-membered rings proved difficult.
Generation of β-Carbonyl Radicals from Cyclopropanol Derivatives by the Oxidation with Manganese(III) 2-Pyridinecarboxylate and Their Reactions with Electron-Rich and -Deficient Olefins

Various β-carbonyl radicals are generated oxidatively from cyclopropanol derivatives by the use of manganese(III) 2-pyridinecarboxylate (Mn(pic)3).These β-carbonyl radicals react with electron-rich olefins such as conjugated silyl enol ethers, a ketene th
