Christensen, Signe M.,Rosenbohm, Christoph,Sorensen, Mads,Larsen, Lotte-Emilie,Wengel, Jesper,Koch, Troels
, p. 1131 - 1133 (2003)
2′-Amino-LNA phosphoramidite (10) was synthesised by means of a new strategy, which is convergent with the synthesis of 2′-oxy-LNA up until a late stage intermediate (1).
Large scale synthesis of 2′-Amino-LNA thymine and 5-methylcytosine nucleosides
Madsen, Andreas Stahl,Jorgensen, Anna Sondergaard,Jensen, Troels Bundgaard,Wengel, Jesper
, p. 10718 - 10728 (2013/02/23)
Thymine intermediate 17 has been synthesized on a multigram scale (50 g, 70 mmol) from starting sugar 1 in 15 steps in an overall yield of 73%, with only 5 purification steps. The key thymine intermediate 18 was obtained from 17 in a single step in 96% yi

Page/Page column 12; 36, (2008/06/13)
A synthesis of [2.2.1]bicyclo nucleosides which is shorter and provides higher overall yields proceeds via the key intermediate of the general formula III, wherein R4 and R5 are, for instance, sulfonates and R7 is, for instance, a halogen or an acetate. F

The invention relates to a novel strategy for the synthesis of Locked Nucleic Acid derivatives, such as α-L-oxy-LNA, amino-LNA, α-L-amino-LNA, thio-LNA, α-L-thio-LNA, seleno-LNA and methylene LNA, which provides scalable high yielding reactions utilising
Synthesis of 2′-amino-LNA: A new strategy
Rosenbohm, Christoph,Christensen, Signe M.,Sorensen, Mads D.,Pedersen, Daniel Sejer,Larsen, Lotte-Emilie,Wengel, Jesper,Koch, Troels
, p. 655 - 663 (2007/10/03)
In this paper we present revised and significantly improved synthetic routes to 2′-amino-LNA (locked nucleic acid). The optimal route is convergent with the synthesis of LNA monomers ("2′-oxy-LNA") via a common intermediate obtained by a mild deacetylatio

The invention relates to a novel strategy for the synthesis of Locked Nucleic Acid derivatives, such as α-L-oxy-LNA, amino-LNA, α-L-amino-LNA, thio-LNA, α-L-thio-LNA, seleno-LNA and methylene LNA, which provides scalable high yielding reactions utilising
Synthesis and evaluation of α-LNA
Christensen,Dalskov,Nielsen
, p. 825 - 828 (2007/10/03)
Three different synthetic routes to the α-configured LNA thymine monomer starting from D-allose or D-arabinose were investigated. The introduction of one or four α-LNA monomers into α-DNA had a destabilizing effect on the duplexes. However, a fully modifi
