Abstract

Synthesis of a 9-mer alpha-L-LNA (alpha-L-ribo configured locked nucleic acid) containing three 9-(2-O,4-C-methylene-alpha-L-ribofuranosyl)adenine nucleotide monomer(s) has been accomplished. The work involved synthesis of the bicyclic adenine nucleoside via a condensation reaction between L-threo-pentofuranose derivative 1 and 6-N-benzoyladenine followed by C2'-epimerization. Hybridization studies demonstrated very strong duplex formation with 9-mer complementary DNA, RNA, LNA and alpha-L-LNA target sequences.
