Extension of the Criegee Rearrangement: Synthesis of Enol Ethers from Secondary Allylic Hydroperoxides
Goodman, Richard M.,Kishi, Yoshito
, p. 5125 - 5127 (2007/10/02)
The Criegee rearrangement has been extended to secondary allylic hydroperoxides, allowing for the selective synthesis of cyclic and acyclic enol ethers; the effect of base and electrophilic agent was studied.
