New phosphitylating reagent in the nucleotide chemistry containing two 4-nitrophenoxy leaving groups. Remarkably fast and clean phosphitylations activated by DBU leading to thio- and seleno-oligonucleotides

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
