- Does it matter whether acetone is added first to the eq. NaOH solution then the benzaldehyde, or if the benzaldehyde is added first to the aq. NaOH solution, then the acetone in an aldol synthesis of dibenzalacetoneneed help with the aldol condensation product1. Discuss the role of the Aldol condensation reaction in the synthesis below. What specific reaction was used in the synthesis? What is the importance of the aldol reaction in the entire synthetic approach? 2. Show the detailed reaction mechanism involved in their corresponding specific parts in this syntheses.
- What is the strongest nucleophile, NH3, CH4, CH3O-, or H2O?The aldol reaction didn't stop after the initial nucleophilic attack followed by protonation of the oxygen, it continued to loss of water across the newly formed bond. Why is this? It was favorable to lose water in order to extend the conjugation of the system. Water is always lost after an aldol reaction. It was favorable to lose water in order to increase solubility of the product. Water was not lost across the newly formed bond.Draw the major product of the aldol addition reaction between two of equivalents of this aldehyde with the conditions provided.
