Ether, allenyl methyl metallation

Alkyl enol ethers can be conveniently prepared by the alkylation of a-methoxyvinyllithium and related metallated enol ethers. In a typical example, methyl vinyl ether (1) is converted by r-butyllithium to give a-methoxyvinyllithium (2). Reaction of (2) with octyl iodide gives the enol ether (3). Metallation of methyl propenyl ether (4) and methyl allenyl ether (5) can be similarly executed. ...
