The Novel 6–(N-Pyrrolyl)purine Acyclic Nucleosides:1H and13C NMR and X-ray Structural Study†
摘要:
Synthesis of the novel nucleoside analogues containing exocyclic pyrrolo moiety and acyclic side chains attached to the purine ring at N-9 and N-7 is described. The site of alkylation was determined by H-1 and C-13 NMR on the basis of chemical shifts, C-H coupling constants and connectivity in NOESY and HETCOR spectra. The N-9 substitution of 7 was proved by its X-ray crystallographic analysis.
