The mononucleotide units (4) was prepared by the action of 2,6-dichlorophenyl 5-chloro-8-quinolyl phosphorochloridate on nucleosides. 2,6-Dichlorophenyl group in the mononucleotide units (4) have been employed as a protecting group for 3′-terminal phosphodiester functions; it is stable under standard operations required for the deoxyribooligonucleotide synthesis and readily removed by the action of
