Implication

Structural chemical analysis reveals keto–enol tautomerism and intramolecular hydrogen bonding in bis(acetoxy)curcumin, confirming stable planar configurations in curcumin derivatives.

Key Points

To determine the molecular structure and hydrogen bonding configuration of bis(acetoxy)curcumin and verify the structural form of curcumin.
Carried out molecular structure analysis of bis(acetoxy)curcumin (C25H24O8).
Performed a structural redetermination of native curcumin to evaluate its tautomeric state.
Bis(acetoxy)curcumin unequivocally adopts the keto–enol form, stabilized exclusively by intramolecular hydrogen bonding.
Curcumin structure redetermination confirms that it also exists in the keto–enol form.
