produced phenyl allyl H-phosphonate and the subsequent ester-exchange with various nucleosides produced nucleoside allyl H-phosphonates. Antherton-Todd reaction of the nucleoside allyl H-phosphonates with 3'-amino-3'-deoxythymidine yielded dideoxyribonucleotide N3'→P5' phosphoramidates, and the repetition of this procedure provided trideoxyribonucleotide N3'→P5' phosphoramidates. The method can be used
苯基二氯化磷与等量的烯丙醇和叔丁醇的 Arbuzov 反应生成苯基烯丙基 H-膦酸酯,随后与各种核苷的酯交换生成核苷烯丙基 H-膦酸酯。核苷烯丙基 H-膦酸酯与 3'-氨基-3'-脱氧胸苷的 Antherton-Todd 反应产生双脱氧核糖核苷酸 N3'→P5' 氨基磷酸酯,重复该过程提供三脱氧核糖核苷酸 N3'→P5' 氨基磷酸酯。该方法可用于合成寡脱氧核糖核苷酸 N3'→P5' 氨基磷酸酯,无需对所有核苷进行任何保护。
