NMR Spectrum
Prediction： 1H spectrum recorded for 1 in d?-DMSO exhibits three singlets at 7.371, 6.845 and 6.374 ppm and a 7-spin complex system between 3.0 and 5.0 ppm. The analysis of this second-order system revealed coupling constants typical of a glucose entity (see, for example, Silva and Pinto, Curr. Med. Chem., 2005, 12: 2481-2497): 4.594 (J= 9.9 Hz, H- 1 ), 4.047 (J= 9.9 and 8.4 Hz, H-2), 3.202 (J= 8.4 and 8.6 Hz, H-3), 3.123 (J= 8.6 and 9.2 Hz, H-4), 3.171 (J = 9.2, 5.9 and 1.8 Hz, H-5), 3.688 (J = 11.8 and 1.8 Hz, H-6a) and 3.406 ppm (J= 11.8 and 5.9 Hz, H-6b).
