phosphate-buffered aqueous media consequently improved the cyclization yields. The ground-state interactions between amidegroups and the terminal COO− group with the imide CO groups were studied for the model system [N-(phthaloyl)glycyl]sarcosine (1) by NMR spectroscopy where the amide (E/Z)-equilibrium depends on the presence of carboxylate vs. free carboxylic acid, demonstrating the role of H-bonding
