alpha-LNA is presented as a stereoisomer of LNA (locked nucleic acid) with alpha-D-configuration. Three different approaches towards the thymine a-LNA monomer as well as the 5-methylcytosine alpha-LNA monomer are presented. Different alpha-LNA sequences have been synthesised and their hybridisation with complementary DNA and RNA has been evaluated by means of thermal stability experiments and circular dichroism spectroscopy. In a mixed pyrimidine sequence, alpha-LNA displays unprecedented parallel-stranded and selective RNA binding. Furthermore, a remarkable selectivity for hybridisation with RNA over DNA is indicated.
