Syntheses of anomeric pairs of new C-nucleosides via 1,3-dipolar cycloaddition reaction, part I

A convenient pathway to a variety of β-and α-C-nucleosides has been developed by utilizing 1,3-dipolar cycloaddition reactions of various exocyclic and endocyclic heterocyclic ylides with β (5a) and α (5b) anomers of ethyl 3-(2',3'-O-isopropylidene-5'-O-trityl-D-ribofuranosyl) propiolate, respectively. Assignment of configuration at C1' position of the C-nucleosides could be made by a comparative study of the properties of corresponding α and β anomers with a reasonable degree of certainity.
