Concept explainers
Interpretation:
Barbituric acid can be prepared from malonic ester and urea as shown. A complete, detailed mechanism for this reaction is to be provided.
Concept introduction:
In the basic solution, no strong acid should appear in the mechanism, hence, the proton transfer step occurs before the nucleophilic addition-elimination reaction. The nucleophilic addition-elimination mechanism has two steps. Step 1 is nucleophilic addition, in which a nucleophile attacks the electron poor carbonyl carbon. This forces the pair of electrons from the initial
