Short Answer

Expert verified

Answer

Step by step solution

01

LDA

Lithium diisopropylamide (LDA) is a strong base with the molecular formula [CH32CH]2NLi. In combination with H2O, it gives directed aldol reaction effectively.

02

Cross-aldol reaction

The base abstracts the hydrogen ion H+ from the enolizable aldehyde to initiate the reaction.

03

Product of the given reaction

a. The product of the given reaction is shown hereunder.
