Abstract :
A novel nine-membered intramolecular hydrogen bonding between ester carbonyl and phenolic hydroxyl groups was investigated based on X-ray crystallography and variable-temperature 1H NMR spectroscopy. The 1H NMR studies in CDCl3 indicated that a significant downfield shift of the phenolic proton as the temperature is lowered.
