title: Protection of 5'-hydroxy functions of nucleosides.
abstract: The 5-hydroxy group is the primary hydroxy group of nucleosides. It is mandatory to protect 5-hydroxyls in all methods of oligonucleotide synthesis that require nucleoside synthons. This unit discusses a wide variety of acid-labile and base-labile protecting groups, as well as enzymatic methods for 5-protection and deprotection.
