title: Synthesis of a 2'-amino-alpha-1-LNA-T phosphoramidite.
abstract: A convergent route to 2'-amino-alpha-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, and 3) separation of alpha-L- and beta-L-configured intermediates.
