Abstract:
The solid-phase synthesis of oligonucleotide derivatives such as phosphorothioates and phosphoroselenoates was investigated. Some ionic liquids containing the trlbexyl(tetradecyl)phosphonium cation and various anions proved to be very effective in dissolving the chalcogens (sulfur and , selenium) and to prepare oligonucleoside chalcogenophosphates. The suitability ofionic liquid-based chalcogen-transfer mixtures for the synthesis of oligonucleoside chalcogenophosphates on solid-phase was evaluated and subsequently the structure-activity relationship studied in detail. The compatibility of ionic liquid-based chalcogen-transfer mixtures with diverse types of solid supports e.g. controlled-pore glass, poly(vinylacetate) and. different synthetic methods. e.g. phosphoramidite and H-phosphonate method makes them useful as replacement of the more expensive and relatively unstable commerciaily avai1able chalcogen-transfer reagents. The distillation of ionic liquids was also studied.
