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.
通过Vassella型硝酮的1,3-偶极环加成反应的策略,设计了2,,3'-二脱氧核苷的4'-氮杂类似物的非对映体和对映体选择性合成。该反应导致(1' - [R )-和(1'小号)-4'-氮杂-2',3'-dideoxythimidine和氟尿苷的类似物,对映体纯的形式。
