摘要：
It was found by H-1, C-13 and N-15 NMR study that substitution of 4,9-dihydro-4, 6-dimethyl-9-oxo-3-(2',3',5'-tri-O-acetyl-beta-D-ribofuranosyl) imidazo [1,2-a]purine (wyosine triacetate, 1) at C2 position with electronegative groups CH3O and C6H5CH2O results in a noticeable electron distribution disturbance in the "left-hand" imidazole ring and a significant increase in the North conformer population of the sugar moiety.
