Triazolyl-DNA ((TL)DNA), a DNA-analog wherein phosphodiester units are replaced by triazole motifs, is of great interest. We have synthesized (TL)DNA oligomers by adopting the Topochemical Azide-Alkyne Cycloaddition (TAAC) reaction. A nucleoside decorated with the azide and alkyne units crystallized with the proximal placement of the azide and alkyne units of the adjacent molecules and underwent the TAAC reaction to form (TL)DNA oligomers.

UI	MeSH Term	Description	Entries
D008958	Models, Molecular	Models used experimentally or theoretically to study molecular shape, electronic properties, or interactions; includes analogous molecules, computer-generated graphics, and mechanical structures.	Molecular Models,Model, Molecular,Molecular Model
D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
