A new protecting group strategy for oligonucleotide synthesis

This thesis describes the development of the various methods available for the synthesis of deoxyoligoribonucleotides. The use of the 2,2-bis (4-nitro-phenyl)ethyl group was investigated, mainly as a 5'-hydroxyl protecting group on 2'-deoxyribonucleotides, but also as a base protecting group for the O4-function of thymidinc and the Nc-exocyclic amine of adenosine. The deprotection conditions required for the removal of this group and its subsequent use in the synthesis of 2'-deoxyribonucleotides utilising phosphoramidite methodology arc described. An investigation, by 81P n.m.r., of the coupling and oxidation steps of the synthesis of DNA is included as well as a brief study of the potential use of zinc iodide as an accelerating agent in the coupling of nuclcotidcs by the phosphotriester method of synthesis.
