[摘要]:This report describes the palladium-catalyzed functionalization of cyclopropanes containing oxazoline, oxime ether, and pyridine directing groups. Three different oxidants were examined in these studies: IOAc, PhI(OAc)(2), and benzoquinone. The reactions yielded products derived from 2 degrees sp(3) C-H functionalization and/or C-C activation of the cyclopropane ring. The outcome and the product distributions were highly dependent on the structure of the substrate and the nature of the oxidant. |
