The application of the phosphorylatingagent 2-chlorophenyl-o,o-bis-[1-benzotriazolyl]-phosphate (HOBT-approach) for the introduction of 3'-5'-phosphotriester linkages between a properly 5'-protected (4,4'-dimethoxytrityl) deoxy-nucleoside and a deoxy-nucleoside having free OH groups is described. In this way, all sixteen partially-protected DNA dimers having a free 3'-OH group have been synthesized
