where B - a residue of thymine, cytosine, adenine or guanine; n = 1-20 that can be used as the parent compounds for synthesis of oligonucleotide reagents for biotechnological aims. Method involves the successive treatment of the parent protected oligonucleotides with iodine solution in an aqueous pyridine followed by treatment with an aqueous ammonia and acetic acid. The parent protected oligonucleotides are 5'-O-dimethoxytrityl,3'-p(S)SMe, N-acyl, P(S)SMe-protected phosphodithioate oligonucleotides of the general formula (III)
