Intermolecular ene reactions utilizing oxazolones and enol ethers
We report herein an intermolecular ene reaction using oxazolones with enol ethers which results in the formation of novel quaternary amino esters in near quantitative yields. The overall reaction transformation closely resembles an intermolecular version of the Conia-ene reaction. The reactions are uncatalyzed and occur under very mild conditions.
