Abstract
An efficient strategy for the synthesis of 2,2-difluoro-2,3-dihydrofuran derivatives from β-fluoroalkyl-β-enaminoketones is described. The reaction occurred via an intramolecular halophilic attack-initiated cascade process. A series of 2,3-dihydrofurans were prepared in high yields. And an intermolecular domino process achieved providing polysubstituted furans. The mechanism of the reaction is discussed.
