Studies on the role of DBU in the reaction of P(III)-OAryl system with nucleoside
Dabkowski,Tworowska,Kazimierczak,Michalski
, p. 467 - 472 (2007/10/03)
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
Synthesis of phosphorofluoridates and phosphorofluoridothioates via the phosphoramidite approach
Dabkowski, Wojciech,Tworowska, Izabela
, p. 866 - 874 (2007/10/03)
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
Dabkowski, Wojciech,Tworowska, Izabela,Michalski, Jan,Cramer, Friedrich
, 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
Synthesis of 2'-Deoxynucleosid-3'-yl-N,N-Diisopropylaminophosphorfluoridites. A New Class of Stable PIII Nucleotides Containing a P-F Bond
Dabkowski, Wojciech,Tworowska, Izabela
, p. 1095 - 1098 (2007/10/02)
A new methodology based on phosphitylating reagents containing 4-nitrophenoxy leaving group has been employed to synthesize stable 5'-O-(4,4'-dimethoxytrityl)nucleosid-3'-yl-N,N-diisopropylaminophosphofluoridites 1a-d.
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
