D. Basavaiah et al., Stereoselective transformation of Baylis-Hillman adducts into (3E)-3-(alkoxymethyl)alk-3-en-2-ones, SYNTHESIS-S, (2), 2000, pp. 217-219
The pure (3E)-3-(methoxymethyl)alk-3-en-2-ones and (3E)-3-(ethoxymethyl) al
k-3-en-2-ones are formed in the acid induced reaction of 4-hydroxy-3-methyl
enealkan-2-ones with methanol and ethanol, respectively.
