Palladium-Mediated Ring Opening of Hydroxycyclopropanes

Abstract
The palladium-mediated ring opening of substituted cyclopropanols has been found to take place predominantly at the less substituted C−C bond. Thus, sequential application of the titanium-mediated cyclopropanation of esters and the palladium-mediated ring opening of the resulting cyclopropanols provides a convenient method for functionalizing monosubstituted olefins.
