A diastereo- and enantioselective synthesis of 4′-aza analogues of 2′,3′-dideoxynucleosides has been designed by the strategy of the 1,3-dipolar cycloaddition reaction of a Vasella-type nitrone. The reaction leads to (1′R)- and (1′S)-4′-aza analogues of 2′,3′-dideoxythimidine and fluorouridine, in enantiomerically pure forms

Abstract
A diastereo- and enantioselective synthesis of 4′-aza analogues of 2′,3′-dideoxynucleosides has been designed by the strategy of the 1,3-dipolar cycloaddition reaction of a Vasella-type nitrone. The reaction leads to (1′R)- and (1′S)-4′-aza analogues of 2′,3′-dideoxythimidine and fluorouridine, in enantiomerically pure formsFile in questo prodotto:
