mild and efficient process for the direct-type catalytic allylation of sulfonylimidates has been developed; this reaction represents the first example of Bronsted base-catalysed, in situ generation and use of alpha-alkyl enolates in substitution reactions; the success of this methodology stems from the tunable alpha-proton acidity and nucleophilicity of sulfonylimidates, which could be harnessed in the
