摘要

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 ...
