  Solution Phase Synthesis of Dithymidine Phosphorodithioate Using New S-Protecting Groups in Combination with a Chemoselective Coupling Reagent (PyNOP)

  摘要：

  A method for the synthesis of O-thymidin-3'-yl S-alkyl dithiophosphate monomers 1 with different S-protecting groups has been developed. These for solution phase synthesis of dithymidine phosphorodithioate by a new method. Coupling reactions are fast (15 min.) and the products phosphorothioate contaminations.

  Synthesis of Oligodeoxynucleoside Phosphoro-Monothioates and Phosphorodithioates by a Phosphotriester Method

  摘要：

  A phosphotriester method for the synthesis of dithymidine phosphoromonothioates and phosphorodithioates with new S-protecting groups has been investigated. Four of the S-protecting groups possesed catalytic activity, however side reactions occurred during deprotection. The best S-protecting group was 4-chloro-2-nitrobenzyl which could be removed with a minimum of side reactions (0.3 %). The coupling reagent PyFNOP (14) gave protected dithymidine phosphoromonothioate in 96 % yield after 15 min coupling. Furthermore PyFNOP chemoselectively activates oxygen in nucleoside phosphorodithioate monomers 9 and can be used for the synthesis of oligodeoxynucleoside phosphorodithioates with mixed base sequences.

  A phosphotriester method has been developed for solid phase synthesis of oligodeoxynucleoside phosphorodithioates. Couplings are performed by chemoselective oxygen activation of protected nucleoside dithiophosphate anions 1, 7, 8, 9 with 4-nitro-6-trifluoromethylbenzotriazol-1-yl-oxy-tris(pyrrolidine)-phosphonium hexafluorophosphate (PyFNOP). Under optimised conditions coupling yields are above 95%
