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-isopropy

1,3-Dipolar cycloaddition of dipolarophiles (1) and (2) with endocyclic heterocyclic azomethine ylides (4), (14) and (24), prepared in situ, leads to the protected β-and α-C-nucleo-sides (7), (8), (17), (18), (27) and (28), respectively. These, on
