Synthesis of fluoroacylated 4,5-dihydrofurans and fluoroalkylated tetrahydrofurans by the radical cyclization using manganese(III) acetate. Part II

Manganese(III) acetate-based radical cyclizations of various fluorinated 1,3-dicarbonyl compounds with alkenes produced 3-fluoroacylated 4,5-dihydrofurans and 2-acetyloxy-2-fluoroalkylated tetrahydrofurans in good yields. Mechanism was proposed for the formation of all compounds. The radical cyclization of fluorinated 1,3-dicarbonyls showed to form different cyclized products depending on the structure of alkenes and enol forms of 1,3-dicarbonyls.
