Question
Chapter 22, Problem 56P
Interpretation Introduction
Interpretation: The stepwise mechanism for the given reaction is to be drawn.
Concept introduction: The Aldol condensation reaction that takes place within the same molecule in presence of strong base is known as intramolecular aldol reactions. This reaction takes place within the dicarbonyl compounds in which one carbonyl group forms the enolate that acts as a nucleophile and reacts with second carbonyl group which acts as electrophile.
