A detailed protocol for preparation 3'-glycoconjugated oligonucleotides is described based on one-pot immobilization of 4,4'-dimethoxytrityl-protected carbohydrates to a solid support followed by on-support peracetylation and automated oligonucleotide assembly. Compared to an appropriate building block approach and post-synthetic manipulation of oligonucleotides, this protocol may simplify the synthesis scheme and increase overall yield of the conjugates. Furthermore, the immobilization to a solid support typically increases the stability of reactants, enabling prolonged storage, and makes subsequent processing convenient. Automated assembly on these carbohydrate-modified supports using conventional phosphoramidite chemistry produces 3'-glycoconjugated oligonucleotides in relatively high yield and purity. © 2020 Wiley Periodicals LLC.
