Graphical Abstract
  • -deazaguanine (c7G), forms a 1:1 complex with pentameric adenyl DNA. Deazaguanine nucleobase was chosen because of the unique glycoside bond stability and its ability to prevent G-quartet formation. To increase the already strong binding of DNG to DNA, DNG was combined with a ligand capable of binding

  • different, in shape and dimension. This clearly indicates the role of the uracil molecule in directing the shape of the channel structure. In conclusion, we have illustrated the molecular recognition process of melamine with nucleobase uracil. We have also established the presence of channels, in the three

Graphical Abstract
  • . The structure of products 13a-c was confirmed by 1H NMR analysis. The ratio of product and 4-methyl derivative is probably influenced by diverse effects of nucleobase on the reaction mechanism, especially the interaction of nucleobases with triphenylphosphine residue in the intermediates I(a-c)-IV(a-c

  • containing three (DNA nucleosides) and four (RNA nucleosides) chiral centers respectively. Though the coordination of metal ions to nucleosides is well known, mostly the nucleobase interacts with the metal centre, and the chiral part of the nucleoside is not involved in the coordination. [1][2] Although a

Conclusion In summary, an effective route for the synthesis of 3
