| Abstract: | 1H and 13C NMR chemical shifts of cis and trans isonucleoside analogues of purine in which the furanose moiety is substituted by a tetrahydropyran ring were completely assigned using one‐ and two‐dimensional NMR experiments that include NOE, DEPT, COSY and HSQC. The significant 1H and 13C NMR signals differentiating between the cis and trans stereoisomers were compared. Copyright © 2010 John Wiley & Sons, Ltd. |
