Graphical Abstract
  • observed for 4 and 5 are quite different to those of the recently described phenanthroline/aminopyridine-based receptors 22 and 23 (see Figure 4) [27][29], which show a strong preference for α-glucoside and α-galactoside vs. the β-anomers. Thus, depending on the nature of the recognition units used as
  • and 5 with these monosaccharides to be much more favorable than those with the α-anomers 7a and 9. The curve fitting of the titration data for 4 and β-glucoside 6a suggested the existence of 1:1 and 2:1 receptor–sugar complexes in CDCl3 solutions with a stronger association constant for 1:1 binding

Graphical Abstract
  • -phosphate is described. Preparations of both the α- and β-phosphonate anomers are reported for the ribose and 5-fluoro-5-deoxyribose series and a synthesis of the corresponding cyclic phostones of each α-ribose is also reported. These compounds have been prepared as tools to probe the details of

  • substitution under the reaction conditions. In each case, the required products (26 and 30) were obtained in moderate (30–37% i.e. 67–71% per step) yield over the three synthetic steps as 66:34 mixtures of anomers. Nevertheless, the yields were deemed acceptable because, over the three steps, significant
  • highly (>95:<5) diastereoselective. Fortunately, the anomers of the bis-allylic alcohols 27, 29 and 33 were separable by careful column chromatography. The stereochemical outcome of the Luche reduction had been remarkable: although the reaction had been highly diastereoselective in both heterocyclic
