Complete assignment of the (1)H and (13)C NMR spectra of cis and trans isonucleoside derivatives of purine with a tetrahydropyran ring.
(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.
