OXIDATIONS BY METHYL TRIFLUOROMETHYL DIOXIRANE. EPOXIDATION OF ENOL ETHERS

Troisi, Luigino,Cassidei, Luigi,Lopez, Luigi,Mello, Rossella,Curci, Ruggero

, p. 257 - 260 (2007/10/02)

Isolated methyl trifluoromethyl dioxirane 4b has been employed to achieve the rapid, low temperature epoxidation of enol ethers, such as alkoxy(aryl)methylidene adamantanes 1a-e and methoxy(2-naphtyl)methylidene 2-bornane 1f, affording the corresponding spirooxiranes in excellent (92-97percent) yields.
