Abstract

5′-O-(p, p′-Dimethoxytrityl)-2′-deoxyribonucleosides without protection of the amino functions, 5-8, are important substances for the synthesis of various kinds of nucleic acid- related derivatives. For example, these compounds are useful as building blocks for oligonucleotide synthesis via the hydroxyl-activation method. 1 They have also served as key intermediates of N-free nucleoside-3′-phosphoramidites2, 3 and-H-phosphonates, 4 ...
