Abstract
Conformational Properties of 5 J-uridinc (I) 5 J-2’-deoxy-uridine(2), 5 J-2’-chlorouridine (3), 5’-AMP-di-Na-salt (4), NAD+ (5) and NADH-di-Na-salt (6) have been investigated by the I3C NMR spectroscopy method. Chemical shifts of carbon atoms of carbohydrate fragments in (5) and (6) are corrected and spin-spin couping constants (SSCC) 3JI3C6-HI’, 3JI3C2-HI’ and 3JI3C8-HI’ as well as glycosidic torsional angles have been determined. It is shown that rotatory isomerism changes with different substituents at C-2’ of a carbohydrate fragment as well as in β,γ pydidine base positions.
