Conclusions
-
1.
Dry Na2CO3 in the presence of TEBA was used to generate carbanions from malonic and acetoacetic esters.
-
2.
The thus generated carbanions undergo Michael addition to acrolein, crotonaldehyde, cinnamaldehyde, and the dimethyl manoacetal of fumaric dialdehyde, but undergo Knoevenagel condensation with citral.
