Abstract
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 thioacetal, a ketene dithioacetal, and a vinyl ether intermolecularly to give crossed-addition products in good yield. Furthermore, the combined use of Mn (pic) 3 and tributylhydridotin makes it possible ...
