We present a very efficient synthetic procedure leading to the phosphorofluoridates RO-P(O)(OH)F 1 or phosphorofluoridothioates RO-P(S)(OH)F 2, which is based on the intermediary of fluorophosphoramidites (RO)P(F)N iPr2 5 [R = 9-(hyd
New efficient synthesis of thymidine cyclic 3′, 5′-phosphorofluoridate and its sulfur analogue via the phosphoroamidite route

, p. 1779 - 1785 (2007/10/03)
We describe the convenient synthesis of thymidine cyclic 3′, 5′-phosphorofluoridate 6, which is superior to that previously reported. Our procedure is based on a sequence of reactions utilizing 3 as the key substrate. Similar sequence of reaction leads to
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
Helinski, Jan,Dabkowski, Wojciech,Michalski, Jan
, p. 6451 - 6454 (2007/10/02)
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
