Abstract

^1^H and ^13^C 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 ^1^H and ^13^C NMR signals differentiating between the cis and trans stereoisomers were compared. Copyright © 2010 John Wiley & Sons, Ltd.
