Palladium-Catalyzed Hydroarylation, Hydroalkenylation, and Hydrobenzylation of Ynol Ethers with Organohalides: A Regio- and Stereoselective Entry to α,β- and β,β-Disubstituted Alkenyl Ethers
Pd-catalyzed reductive addition of organohalides, including aryl, alkenyl, and benzyl halides, to ynol ethers has been realized in the presence of 2-propanol, giving α,β- and β,β-disubstituted olefinic ethers in satisfactory yields with excellent regio- and stereoselectivity. It represents the first highlyregio- and stereoselective hydroarylation, hydroalkenylation, and hydrobenzylation of ynol ethers.
