Abstract: | A new, versatile phosphorylating agent, bis2-(p-nitrophenyl)ethyl] phosphorochloridate ( 3 ), has been prepared and is used for 3′- and/or 5′-phosphorylations of nucleosides. The resulting bis2-(p-nitrophenyl)ethyl] phosphotriesters are versatile synthons in oligonucleotide synthesis leading finally to 3′- and/or 5′-terminated monophosphates in excellent yields. |
