Studies have been reported on the tautomerism of 3-acetyltetramic acids. These compounds can occur in enolic tautomers A/B and C/D, in addition to tautomers A-D. Tautomers A/B and C/D are rapidly interconverted, and the NMR spectra show signals, in which chemical shifts are weighted averages of those tautomers. The interconversion between tautomers A-D is a slow process on the NMR timescale, and separate NMR signals are detected: a) M. J. Nolte, P. S. Steyn, P. L. Wessels, J. Chem. Soc.
