Synthesis and biophysical studies of short oligodeoxynudeotides with novel modifications: a possible approach to the problem of mixed base oligodeoxynudeotide synthesis

Abstract

The syntheses of 1,2-dideoxy-D-ribofuranose and 1,2-dideoxy-1-phenyl-beta-D-ribofuranose are described. Oligodeoxynucleotides containing these analogues have been synthesised and hybridized to their complementary strands. Hypochromicity studies have shown that these duplices are less stable than either the totally complementary duplex or those containing A.C and G.T mismatches.
