The main purpose of this article is to discuss 2′-protection in the context of effective oligoribonucleotide synthesis. Emphasis is placed on the 2′-protecting groups of choice in the synthesis of oligo-and polyribonucleotides, and the requirements that a protective group must satisfy to become the 2′-hydroxyl-protecting group of choice. Finally, the unit discusses the issue of 2′-O-acyl and 2′-O-silyl group migration to the 3′-hydroxy function of ribonucleosides during protection, along with the consequences of the conditions used for their removal on the stability of internucleotide linkages.
