A new approach to oligonucleotide N3′→P5′ phosphoramidate building blocks
摘要:
A new synthetic approach to 5'-phosphoramidites of 3'-aminonucleosides was developed. The methodology relics upon the use of 3'-amino-2',3'-dideoxynucleosides as the key starting materials. The final products were obtained in high yields via 2-3-step processes using selective introduction of orthogonal protective groups to the 3'-aminonucleoside sugar and base moieties.
