    • The ratio of cyclic forms was calculated by the integration of anomeric proton signals in the 1H NMR spectrum, with the peak assignments being made by 1H-1H COSY and HMQC experiments. Assignment of anomeric carbon signals in the 13C NMR spectrum was done by comparison with published data for D-idose (Bock, K, Pedersen, C. Adv. Carbohydr. Chem. Biochem. 1983, 41, 27-66, Anomeric proton resonances: 5.51 ppm (3J1,2, 4.8 Hz, correlated to 13C signal at 97.7 ppm; β-furanose, 5.25 ppm, 3J1,2, 2.6 Hz, correlation to 13C signal at 94.1 ppm; α-pyranose, 5.17 ppm 3J1,2, 2.1 Hz, correlated to 13C signal at 103.5 ppm; a-furanose, 5.08 ppm, 3J1,2, 4.1 Hz, correlation to 13C signal at 95.3 ppm; β-pyranose

    • H2,H3 = 6.2 Hz, suggesting that other ring conformers are present. Nevertheless, we feel the ratio of cyclic forms can be rationalized by these simple steric arguments.
