93. Nucleotides: Part XLVIII. Synthesis of 2′-amino-2′-deoxyarabinonucleoside phosphoramidite building blocks

Chemical syntheses of 2′-amino-2′-deoxyarabinonucleosides of uracil, thymine, cytosine, adenine, and guanine and their conversion into suitably protected 3′-phosphoramidite building blocks 24-28 for oligonucleotide synthesis are described. The 2-(4-nitrop
