A new synthetic approach to modified oligonucleotides based on N,N′-diisopropyl-di-(4-nitrophenyl)phosphoroamidite 1 is described. The procedure involves displacement of either 4-nitrophenoxy or diisopropylamino ligands. The former proceeds very fast in t
Studies on the role of DBU in the reaction of P(III)-OAryl system with nucleoside

The involvement of a (=P-N≡)+ cationic species has been unambiguously demonstrated in the phosphitylation of nucleosides in the presence of DBU (1,8-diazabicyclo-[5.4.0]undec-7-ene) by 31P NMR spectroscopy and its reaction with benzo
