By the use of a convergent approach based on 1,3-dipolar cycloaddition reactions between N-protected formylnitrones generated in situ and 1-N-vinyluracil, a new class of 4'-aza-analogues of 2',3'-dideoxynucleosides is synthesized. Competitive reaction for the endocyclic bond of uracil also brings to a new isoxazolidine derivative fused with the pyrimidine nucleus.
通过使用基于在原位产生的N-保护的甲酰基硝酮和1-N-乙烯基尿嘧啶之间的1,3-偶极环加成反应的收敛方法,得到了新的2',3'-二脱氧核苷类4'-氮杂类似物。合成的。尿嘧啶内环键的竞争反应也带来了与嘧啶核融合的新异恶唑烷衍生物。
