Relevant academic research and scientific papers

Synthesis and hybridization studies of 2′-amino-α-L-LNA and tetracyclic "locked LNA"

A convergent route to a new class of locked nucleic acids, i.e., 2′-amino-α-L-LNA, has been developed. The optimized synthetic route to the corresponding phosphoramidite building block of thymine proceeds in 4% overall yield over 15 steps from the startin

Synthesis of a 2′-amino-α-L-LNA-T phosphoramidite

A convergent route to 2′-amino-α-L-LNA-T phosphoramidite building block 16 has been developed. Key steps include 1) introduction of a C2-azido group prior to nucleobase-coupling, 2) tandem Staudinger and intramolecular nucleophilic substitution reaction,
