Synthesis and Anti-HIV Activity of Novel Cyclopentenyl Nucleoside Analogues of 8-Azapurine

Synthesis of beta-hydroxyphosphonate and 1,2-dihydroxy acyclic nucleoside analogs via 1,3-dipolar cycloaddition strategy

A convenient synthetic approach toward nucleoside analogs where beta-hydroxyphosphonate- or 1,2-dihydroxy units are connected to the nucleic acid base through a triazole spacer is discussed.

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.
