Abstract
Click chemistry has provided us with access to DNA and RNA analogues with non-natural triazole internucleoside linkages. The bond periodicity of the oligonucleotides was designed to enforce duplex formation with natural congeners, and the non-cleavable linkages protect the oligomers against nuclease digestion. This account reviews the progress of the triazole-linked analogues over the past five years. Reinforced by their synthetic robustness, these analogues may find various utilities as tools for exploratory research.
