Abstract

The synthesis of a series of 2'-deoxyuridine analogues modified at the 5-position and a series of 2'-deoxypurines modified at the 8-position is described. Ultraviolet melting studies have been used to assess the stability of DNA duplexes 12- and 8-residues in length that contain these modifications. Of those modified residues which have been incorporated into oligonucleotides, 5-(prop-1-ynyl)-2'-deoxyuridine is found to impart the greatest increase in stability on the DNA duplexes studied.
