title: [Automated synthesis of oligodeoxyribonucleotides with terminal phosphate groups].
abstract: 3'- and 5'-phosphorylated oligodeoxyribonucleotides have been synthesized on the "Victoria-4M" automatic synthesizer by phosphoramidite method. Two approaches have been suggested: introduction of a terminal ribo-unit as a potential source of phosphate group or the use of hydroxyl-containing polymer supports which loose the end product of the synthesis via beta-elimination reaction. Yields of oligonucleotides obtained according to both schemes proved to be almost identical. Using the first approach, oligonucleotides containing units with altered configuration of the sugar (xylo-thymidine and arabino-uridine) have been obtained.
