 Title    Syntheses of Anomeric Pairs of New C-Nucleosides via 1,3-Dipolar Cycloaddition Reaction, Part I  
 Abstract    A convenient pathway to a variety of ß-and a-C-nucleosides has been developed by utiliz­ ing 1,3-dipolar cycloaddition reactions of various exocyclic and endocyclic heterocyclic ylides with ß (5a) and a (5b) anomers of ethyl 3-(2',3'-0-isopropylidene-5'-0-trityl-D-ribofurano-syl) propiolate, respectively. Assignment of configuration at exposition of the C-nucleosides could be made by a comparative study of the properties of corresponding a and ß anomers with a reasonable degree of certainity.
