摘要：
Gamma-methylene derivatives of alpha,beta-unsaturated ketones are obtained readily by a one-pot procedure exploiting the reaction of O-silylated dienolates with commercially available formaldehyde N,N-dimethyliminium chloride in anhydrous N,N-dimethylformamide, in situ oxidation of the Mannich reaction product with hydrogen peroxide, and elimination of N,N-dimethylhydroxylamine from the resultant N-oxide.
