2'-Amino-locked nucleic acid (ALNA), maintains excellent duplex stability, and the nitrogen at the 2'-position is an attractive scaffold for functionalization. Herein, a facile and efficient method for the synthesis of various 2'- N -acyl amino-LNA derivatives by direct acylation of the 2'-amino moiety contained in the synthesized oligonucleotides and its fundamental properties are described. The introduction of the acylated amino-LNA enhances the potency of the molecules as therapeutic anti-microRNA oligonucleotides.
