Catalyzed Reactions of Enol Ethers with SN1 Active Groups: A Novel Method for the Preparation of α-Alkylated Ketones
The performance of tert-alkylations, alkoxyalkylations, and aldehyde enolate allylations proceeding with low catalyst loading (0.1 mol % - 5 mol %) is described. The reactions are complete within short times and can even be performed without solvent and under ambient conditions. The mechanism of the reaction was investigated by deuterium labeling and cross-over studies.
