Abstract

DELGADO, Guillermo  and  KRISHNAMURTHY, Ramanarayanan. Assignment of the ¹H and ¹³C NMR spectra of N²,N⁶-dibenzoyl-N²,N⁹-bis(2',3'-di-O-benzoyl-(α)-L-threofuranosyl)-2,6-diaminopurine. Rev. Soc. Quím. Méx [online]. 2003, vol.47, n.3, pp.216-220. ISSN 0583-7693.

The complete ¹H- and ¹³C NMR-chemical shifts assignments of the title 2,6-diaminopurine nucleoside are described. Spectroscopic analysis confirmed the R- configuration at the anomeric carbons and that both the threofuranoses exist in a conformational equilibrium at room temperature.

Keywords : ¹H and ¹³C NMR spectroscopy; 2,6-diaminopurine; nucleosidation; (α)-L-threofuranose; nucleosides, N2,N6-dibenzoyl-N2,N9-bis(2',3'-di-O-benzoyl-(α)-L-threofuranosyl)-2,6-diaminopurine; TNA.
