Continuing our interest in the application of alkali enolates in synthetic organic chemistry, we developed a new methodology providing an easy access to potassium enolates.1 The regioselectivity, γ-1,2- versus γ-1,4- addition, in the addition of potassium prenal dienolate to α,β- unsaturated aldehydes was investigated,2 and was found to be highly selective for a γ-1,2-addition. However, in some cases, the γ-1,4- addition product cannot be avoided.2 ...
