Interpretation:
A mechanism for the base catalyzed isomerisation of the minor product formed in the intramolecular aldo cyclization of 2, 5-heptanedione into the major product upon treatment with aqueous NaOH is to be proposed.
Concept introduction:
The steps involved in the conversion required are i) Attack of the hydroxide ion on α, β-unsaturated
To give:
A mechanism for the base catalyzed isomerisation of the minor product formed in the intramolecular aldo cyclization of 2, 5-heptanedione into the major product upon treatment with aqueous NaOH is to be proposed.
